-This document walks you through a complete HA setup of two VyOS machines. This -design is based on a VM as the primary router, and a physical machine as a -backup, using VRRP, BGP, OSPF and conntrack sharing. - -The aim of this document is to walk you through setting everything up so you -and up at a point where you can reboot any machine and not lose more than a few -seconds worth of connectivity. - -Design -====== - -This is based on a real life, in production design. One of the complex issues -is ensuring you have redundant data INTO your network. We do this with a pair -of Cisco Nexus switches, and using Virtual PortChannels that are spanned across -them. This as an added bonus, also allows for complete switch failure without -an outage. How you achieve this yourself is left as an exercise to the reader -but our setup is documented here. - -Walkthrough suggestion ----------------------- - -The ``commit`` command is implied after every section. If you make an error, -``commit`` will warn you and you can fix it before getting too far into things. -Please ensure you commit early and commit often. - -If you are following through this document, it is strongly suggested you -complete the entire document, ONLY doing the virtual router1 steps, and then -come back and walk through it AGAIN on the backup hardware router. - -This ensures you don't go to fast, or miss a step. However, it will make your -life easier to configure the fixed IP address and default route now on the -hardware router. - -Example Network ---------------- - -In this document, we have been allocated 203.0.113.0/24 by our upstream -provider, which we are publishing on VLAN100. - -They want us to establish a BGP session to their routers on 192.0.2.11 and -192.0.2.12 from our routers 192.0.2.21 and 192.0.2.22. They are AS 65550 and -we are AS65551. - -Our routers are going to have a floating IP address of 203.0.113.1, and use -.2 and .3 as their fixed IPs. - -We are going to use 10.200.201.0/24 for an 'internal' network on VLAN201. - -When traffic is originated from the 10.200.201.0/24 network, it will be -masqueraded to 203.0.113.1 - -For connection between sites, we are running a WireGuard link to two REMOTE -routers, and using OSPF over those links to distribute routes. That remote -site is expected to send traffic from anything in 10.201.0.0/16 - -VLANs ------ - -These are the vlans we wll be using: - -* 50: Upstream, using the 192.0.2.0/24 network allocated by them. -* 100: 'Public' network, using our 203.0.113.0/24 network. -* 201: 'Internal' network, using 10.200.201.0/24 - -Hardware --------- - -* switch1 (Nexus 10gb Switch) -* switch2 (Nexus 10gb Switch) -* compute1 (VMware ESXi 6.5) -* compute2 (VMware ESXi 6.5) -* compute3 (VMware ESXi 6.5) -* router2 (Random 1RU machine with 4 NICs) - -Note that router1 is a VM that runs on one of the compute nodes. - -Network Cabling ---------------- - -* From Datacenter - This connects into port 1 on both switches, and is tagged - as VLAN 50 -* Cisco VPC Crossconnect - Ports 39 and 40 bonded between each switch -* Hardware Router - Port 8 of each switch -* compute1 - Port 9 of each switch -* compute2 - Port 10 of each switch -* compute3 - Port 11 of each switch - -This is ignoring the extra Out-of-band management networking, which should be -on totally different switches, and a different feed into the rack, and is out -of scope of this. - -.. note:: Our implementation uses VMware's Distributed Port Groups, which allows - VMware to use LACP. This is a part of the ENTERPRISE licence, and is not - available on a Free licence. If you are implementing this and do not have - access to DPGs, you should not use VMware, and use some other virtualization - platform instead. - - -Basic Setup (via console) -========================= - -Create your router1 VM so it is able to withstand a VM Host failing, or a -network link failing. Using VMware, this is achieved by enabling vSphere DRS, -vSphere Availability, and creating a Distributed Port Group that uses LACP. - -Many other Hypervisors do this, and I'm hoping that this document will be -expanded to document how to do this for others. - -Create an 'All VLANs' network group, that passes all trunked traffic through -to the VM. Attach this network group to router1 as eth0. - -.. note:: VMware: You must DISABLE SECURITY on this Port group. Make sure that - ``Promiscuous Mode``\ , ``MAC address changes`` and ``Forged transmits`` are - enabled. All of these will be done as part of failover. - -Bonding on Hardware Router --------------------------- - -Create a LACP bond on the hardware router.

With RAs, Your devices will automatically find the - information they need for routing and DNS. - -Multiple LAN/DMZ Setup -====================== - -In this, you use the `Routed /48` information.

Walkthrough +############################# + +This document walks you through a complete HA setup of two VyOS machines. This +design is based on a VM as the primary router, and a physical machine as a +backup, using VRRP, BGP, OSPF and conntrack sharing. + +The aim of this document is to walk you through setting everything up so you +and up at a point where you can reboot any machine and not lose more than a few +seconds worth of connectivity. + +Design +====== + +This is based on a real life, in production design. One of the complex issues +is ensuring you have redundant data INTO your network. We do this with a pair +of Cisco Nexus switches, and using Virtual PortChannels that are spanned across +them. This as an added bonus, also allows for complete switch failure without +an outage. How you achieve this yourself is left as an exercise to the reader +but our setup is documented here. + +Walkthrough suggestion +---------------------- + +The ``commit`` command is implied after every section. If you make an error, +``commit`` will warn you and you can fix it before getting too far into things. +Please ensure you commit early and commit often. + +If you are following through this document, it is strongly suggested you +complete the entire document, ONLY doing the virtual router1 steps, and then +come back and walk through it AGAIN on the backup hardware router. + +This ensures you don't go to fast, or miss a step. However, it will make your +life easier to configure the fixed IP address and default route now on the +hardware router. + +Example Network +--------------- + +In this document, we have been allocated 203.0.113.0/24 by our upstream +provider, which we are publishing on VLAN100. + +They want us to establish a BGP session to their routers on 192.0.2.11 and +192.0.2.12 from our routers 192.0.2.21 and 192.0.2.22. They are AS 65550 and +we are AS65551. + +Our routers are going to have a floating IP address of 203.0.113.1, and use +.2 and .3 as their fixed IPs. + +We are going to use 10.200.201.0/24 for an 'internal' network on VLAN201. + +When traffic is originated from the 10.200.201.0/24 network, it will be +masqueraded to 203.0.113.1 + +For connection between sites, we are running a WireGuard link to two REMOTE +routers, and using OSPF over those links to distribute routes. That remote +site is expected to send traffic from anything in 10.201.0.0/16 + +VLANs +----- + +These are the vlans we wll be using: + +* 50: Upstream, using the 192.0.2.0/24 network allocated by them. +* 100: 'Public' network, using our 203.0.113.0/24 network. +* 201: 'Internal' network, using 10.200.201.0/24 + +Hardware +-------- + +* switch1 (Nexus 10gb Switch) +* switch2 (Nexus 10gb Switch) +* compute1 (VMware ESXi 6.5) +* compute2 (VMware ESXi 6.5) +* compute3 (VMware ESXi 6.5) +* router2 (Random 1RU machine with 4 NICs) + +Note that router1 is a VM that runs on one of the compute nodes. + +Network Cabling +--------------- + +* From Datacenter - This connects into port 1 on both switches, and is tagged + as VLAN 50 +* Cisco VPC Crossconnect - Ports 39 and 40 bonded between each switch +* Hardware Router - Port 8 of each switch +* compute1 - Port 9 of each switch +* compute2 - Port 10 of each switch +* compute3 - Port 11 of each switch + +This is ignoring the extra Out-of-band management networking, which should be +on totally different switches, and a different feed into the rack, and is out +of scope of this. + +.. note:: Our implementation uses VMware's Distributed Port Groups, which allows + VMware to use LACP. This is a part of the ENTERPRISE licence, and is not + available on a Free licence. If you are implementing this and do not have + access to DPGs, you should not use VMware, and use some other virtualization + platform instead. + + +Basic Setup (via console) +========================= + +Create your router1 VM so it is able to withstand a VM Host failing, or a +network link failing. Using VMware, this is achieved by enabling vSphere DRS, +vSphere Availability, and creating a Distributed Port Group that uses LACP. + +Many other Hypervisors do this, and I'm hoping that this document will be +expanded to document how to do this for others. + +Create an 'All VLANs' network group, that passes all trunked traffic through +to the VM. Attach this network group to router1 as eth0. + +.. note:: VMware: You must DISABLE SECURITY on this Port group. Make sure that + ``Promiscuous Mode``\ , ``MAC address changes`` and ``Forged transmits`` are + enabled. All of these will be done as part of failover. + +Bonding on Hardware Router +-------------------------- + +Create a LACP bond on the hardware router.

This is the default assignment. In IPv6-land, it's good for a + single "LAN", and is somewhat equivalent to a /24. + Example: `2001:470:xxxx:xxxx::/64` +- Routed /48. This is something you can request by clicking the "Assign /48" + link in the Tunnelbroker.net tunnel config. It allows you to have up to 65k + LANs. Example: `2001:470:xxxx::/48` + +Unlike IPv4, IPv6 is really not designed to be broken up smaller than /64. So +if you ever want to have multiple LANs, VLANs, DMZ, etc, you'll want to ignore +the assigned /64, and request the /48 and use that. + +Single LAN Setup +================ + +Single LAN setup where eth1 is your LAN interface.

This is an IPv6 alternative for DHCP (though + DHCPv6 can still be used). With RAs, Your devices will automatically find the + information they need for routing and DNS. + +Multiple LAN/DMZ Setup +====================== + +In this, you use the `Routed /48` information. This allows you to assign a +different /64 to every interface, LAN, or even device. Or you could break your +network into smaller chunks like /56 or /60. + +The format of these addresses: + +- `2001:470:xxxx::/48`: The whole subnet. xxxx should come from Tunnelbroker. +- `2001:470:xxxx:1::/64`: A subnet suitable for a LAN +- `2001:470:xxxx:2::/64`: Another subnet +- `2001:470:xxxx:ffff:/64`: The last usable /64 subnet. + +In the above examples, 1,2,ffff are all chosen by you.

That flow is what I refer to as a +zone-pair-direction. eg. A->B and B->A are two zone-pair-destinations. + +Ruleset are created per zone-pair-direction. + +I name rule sets to indicate which zone-pair-direction they represent. +eg. ZoneA-ZoneB or ZoneB-ZoneA. LAN-DMZ, DMZ-LAN. + +In VyOS, you have to have unique Ruleset names. In the event of overlap, +I add a "-6" to the end of v6 rulesets. eg. LAN-DMZ, LAN-DMZ-6. This +allows for each auto-completion and uniqueness. + +In this example we have 4 zones. LAN, WAN, DMZ, Local. The local zone is +the firewall itself. + +If your computer is on the LAN and you need to SSH into your VyOS box, +you would need a rule to allow it in the LAN-Local ruleset. If you want +to access a webpage from your VyOS box, you need a rule to allow it in +the Local-LAN ruleset. + +In rules, it is good to keep them named consistently. As the number of +rules you have grows, the more consistency you have, the easier your +life will be. + +.. code-block:: none + + Rule 1 - State Established, Related + Rule 2 - State Invalid + Rule 100 - ICMP + Rule 200 - Web + Rule 300 - FTP + Rule 400 - NTP + Rule 500 - SMTP + Rule 600 - DNS + Rule 700 - DHCP + Rule 800 - SSH + Rule 900 - IMAPS + +The first two rules are to deal with the idiosyncrasies of VyOS and +iptables. + +Zones and Rulesets both have a default action statement. When using +Zone-Policies, the default action is set by the zone-policy statement +and is represented by rule 10000. + +It is good practice to log both accepted and denied traffic. It can save +you significant headaches when trying to troubleshoot a connectivity +issue. + +To add logging to the default rule, do: + +.. code-block:: none + + set firewall name enable-default-log + + +By default, iptables does not allow traffic for established session to +return, so you must explicitly allow this. I do this by adding two rules +to every ruleset. 1 allows established and related state packets through +and rule 2 drops and logs invalid state packets. We place the +established/related rule at the top because the vast majority of traffic +on a network is established and the invalid rule to prevent invalid +state packets from mistakenly being matched against other rules. Having +the most matched rule listed first reduces CPU load in high volume +environments. Note: I have filed a bug to have this added as a default +action as well. + +''It is important to note, that you do not want to add logging to the +established state rule as you will be logging both the inbound and +outbound packets for each session instead of just the initiation of the +session. Your logs will be massive in a very short period of time.'' + +In VyOS you must have the interfaces created before you can apply it to +the zone and the rulesets must be created prior to applying it to a +zone-policy. + +I create/configure the interfaces first. Build out the rulesets for each +zone-pair-direction which includes at least the three state rules. Then +I setup the zone-policies. + +Zones do not allow for a default action of accept; either drop or +reject. It is important to remember this because if you apply an +interface to a zone and commit, any active connections will be dropped. +Specifically, if you are SSH’d into VyOS and add local or the interface +you are connecting through to a zone and do not have rulesets in place +to allow SSH and established sessions, you will not be able to connect. + +The following are the rules that were created for this example (may not +be complete), both in IPv4 and IPv6.

This mode is easiest for configuration and mostly used when a peer has a public static IP address; +* Hostname. This mode is similar to IP address, only you define DNS name instead of an IP. Could be used when a peer has a public IP address and DNS name, but an IP address could be changed from time to time; +* Remote ID of the peer. In this mode, there is no predefined remote address nor DNS name of the peer. This mode is useful when a peer doesn't have a publicly available IP address (NAT between it and VyOS), or IP address could be changed. + +Each site-to-site peer has the next options: + +* ``authentication`` - configure authentication between VyOS and a remote peer. Suboptions: + + * ``id`` - ID for the local VyOS router. If defined, during the authentication it will be send to remote peer; + + * ``mode`` - mode for authentication between VyOS and remote peer: + + * ``pre-shared-secret`` - use predefined shared secret phrase, must be the same for local and remote side; + + * ``rsa`` - use simple shared RSA key. The key must be defined in the ``set vpn rsa-keys`` section; + + * ``x509`` - use certificates infrastructure for authentication. + + * ``pre-shared-secret`` - predefined shared secret. Used if configured ``mode pre-shared-secret``; + + * ``remote-id`` - define an ID for remote peer, instead of using peer name or address. Useful in case if the remote peer is behind NAT or if ``mode x509`` is used; + + * ``rsa-key-name`` - shared RSA key for authentication. The key must be defined in the ``set vpn rsa-keys`` section; + + * ``use-x509-id`` - use local ID from x509 certificate. Cannot be used when ``id`` is defined; + + * ``x509`` - options for x509 authentication mode: + + * ``ca-cert-file`` - CA certificate file. Using for authenticating remote peer; + + * ``cert-file`` - certificate file, which will be used for authenticating local router on remote peer; + + * ``crl-file`` - file with the Certificate Revocation List. Using to check if a certificate for the remote peer is valid or revoked; + + * ``key`` - a private key, which will be used for authenticating local router on remote peer: + + * ``file`` - path to the key file; + + * ``password`` - passphrase private key, if needed. + +* ``connection-type`` - how to handle this connection process. Possible variants: + + * ``initiate`` - do initial connection to remote peer immediately after configuring and after boot. In this mode the connection will not be restarted in case of disconnection, therefore should be used only together with DPD or another session tracking methods; + + * ``respond`` - do not try to initiate a connection to a remote peer. In this mode, the IPSec session will be established only after initiation from a remote peer. Could be useful when there is no direct connectivity to the peer due to firewall or NAT in the middle of the local and remote side. + +* ``default-esp-group`` - ESP group to use by default for traffic encryption. Might be overwritten by individual settings for tunnel or VTI interface binding; + +* ``description`` - description for this peer; + +* ``dhcp-interface`` - use an IP address, received from DHCP for IPSec connection with this peer, instead of ``local-address``; + +* ``force-encapsulation`` - force encapsulation of ESP into UDP datagrams. Useful in case if between local and remote side is firewall or NAT, which not allows passing plain ESP packets between them; + +* ``ike-group`` - IKE group to use for key exchanges; + +* ``ikev2-reauth`` - reauthenticate remote peer during the rekeying process. Can be used only with IKEv2: + + * ``yes`` - create a new IKE_SA from the scratch and try to recreate all IPsec SAs; + + * ``no`` - rekey without uninstalling the IPsec SAs; + + * ``inherit`` - use default behavior for the used IKE group. + +* ``local-address`` - local IP address for IPSec connection with this peer. If defined ``any``, then an IP address which configured on interface with default route will be used; + +* ``tunnel`` - define criteria for traffic to be matched for encrypting and send it to a peer: + + * ``disable`` - disable this tunnel; + + * ``esp-group`` - define ESP group for encrypt traffic, defined by this tunnel; + + * ``local`` - define a local source for match traffic, which should be encrypted and send to this peer: + + * ``port`` - define port. Have effect only when used together with ``prefix``; + + * ``prefix`` - IP network at local side. + + * ``protocol`` - define the protocol for match traffic, which should be encrypted and send to this peer; + + * ``remote`` - define the remote destination for match traffic, which should be encrypted and send to this peer: + + * ``port`` - define port. Have effect only when used together with ``prefix``; + + * ``prefix`` - IP network at remote side. + +* ``vti`` - use a VTI interface for traffic encryption. Any traffic, which will be send to VTI interface will be encrypted and send to this peer. Using VTI makes IPSec configuration much flexible and easier in complex situation, and allows to dynamically add/delete remote networks, reachable via a peer, as in this mode router don't need to create additional SA/policy for each remote network: + + * ``bind`` - select a VTI interface to bind to this peer;
