T5530: isis: Adding loop free alternate feature
|
|
pppoe: T5630: allow to specify MRU in addition to already configurable MTU
|
|
enables log capabilities for default-action in base chains. And of course, add option for enabling log for default-action
|
|
Add `policy local-route` source and destination port
set policy local-route rule 23 destination port '222'
set policy local-route rule 23 protocol 'tcp'
set policy local-route rule 23 set table '123'
set policy local-route rule 23 source port '8888'
% ip rule show prio 23
23: from all ipproto tcp sport 8888 dport 222 lookup 123

Set the MRU (Maximum Receive Unit) value to n. PPPd will ask the peer to send
packets of no more than n bytes. The value of n must be between 128 and 16384,
the default was always 1492 to match PPPoE MTU.
A value of 296 works well on very slow links (40 bytes for TCP/IP header + 256
bytes of data). Note that for the IPv6 protocol, the MRU must be at least 1280.
CLI:
set interfaces pppoe pppoe0 mru 1280

Add support for per-service cache management for ddclient providers
via `wait-time` and `expiry-time` options. This allows for finer-grained
control over how often a service is updated and how long the hostname
will be cached before being marked expired in ddclient's cache.
More specifically, `wait-time` controls how often ddclient will attempt
to check for a change in the hostname's IP address, and `expiry-time`
controls how often ddclient to a forced update of the hostname's IP
address.
These options intentionally don't have any default values because they
are provider-specific. They get treated similar to the other provider-
specific options in that they are only used if defined.

T5165: Migrate policy local-route rule x destination to address
|
|
ddclient: T5612: Miscellaneous improvements and fixes for dynamic DNS
|
|
Migrate policy local-route <destination|source> to node address
replace 'policy local-route{v6} rule <tag> destination|source <x.x.x.x>'
=> 'policy local-route{v6} rule <tag> destination|source address <x.x.x.x>'

filter and in policy route.

This commit adds a new configuration option to the mDNS repeater service
to allow controlling which IP version to use for mDNS repeater.
Additionally, publishing AAAA record over IPv4 and A record over IPv6 is
disabled as suggested.

T5217: Add firewall synproxy
|
|
conntrack: T5376: T5598: Restore kernel conntrack helpers
|
|
firewall: T5614: Add support for matching on conntrack helper
|
|
ipsec: T5606: Add support for whole CA chains
|
|
Add option `protocol` for policy local-route
set policy local-route rule 100 destination '192.0.2.12'
set policy local-route rule 100 protocol 'tcp'
set policy local-route rule 100 set table '100'
|
|
`nf_conntrack_helper` that auto-assigned helpers is removed from the kernel
|
|
|
|
Also includes an update to smoketest to verify
|
|
Additional cleanup and refactoring for ddclient scripts including the
smotektests.
|
|
Some porvides (like 'namecheap') allow to use '@' or '*' as hostname
prefix for apex and wildcard records. This commit relaxes the hostname
validation to allow these prefixes.
|
|
Enable TTL support for web-service based protocols in addition to
RFC2136 based (nsupdate) protocol.
Since TTL is not supported by all protocols, and thus cannot have a
configuration default, the existing XML snippet `include/dns/time-to-live.xml.i`
does not have common `<defaultValue>300</defaultValue>` anymore and is
instead added explicitly whenever necessary.
|
|
Fix VRF support interface definition and configuration mode for ddclient
to actually capture the VRF name and pass it to the template.
|
|
Add ability to SYNPROXY connections
It is useful to protect against TCP SYN flood attacks and port-scanners
set firewall global-options syn-cookies 'enable'
set firewall ipv4 input filter rule 10 action 'synproxy'
set firewall ipv4 input filter rule 10 destination port '22'
set firewall ipv4 input filter rule 10 inbound-interface interface-name 'eth1'
set firewall ipv4 input filter rule 10 protocol 'tcp'
set firewall ipv4 input filter rule 10 synproxy tcp mss '1460'
set firewall ipv4 input filter rule 10 synproxy tcp window-scale '7'

A `backup` server can be defined to take over in the case of all other
backends failing
set load-balancing reverse-proxy backend <tag> server <tag> address '192.0.2.3'
set load-balancing reverse-proxy backend <tag> server <tag> port '8883'
set load-balancing reverse-proxy backend <tag> server <tag> backup

Also updates flowtable smoketest to verify conntrack enabled

- Add required offload setting for interfaces + flowtable offload (hw-tc-offload)
- Verification of interface support for hardware offloaded flowtables
|

`set firewall flowtable <name> interface <ifname>`
`set firewall flowtable <name> offload [software|hardware]`
`set firewall [ipv4|ipv6] forward filter rule N action offload`
`set firewall [ipv4|ipv6] forward filter rule N offload-target <name>`

T5590: firewall log rule: fix order which rule are processed
|
|
conntrack: T5571: Refactor conntrack using vyos.configdep
|
|
- Moves MSS node out of `tcp-flags.xml.i` and into `tcp-mss.xml.i`
- Update smoketest to verify TCP flag matching
|
|
should be added at the end of the rule, after all matchers and befora action. Also change 2 lines in policy_route smoketest, which suddenly wasn't working as expected

After commit 0ccbbca01b ("openvpn: T3214: specify nopool on --server line only
if needed") that removed the net30 option and nopool smoketests needed a fix.
|
|
T5561: nat: inbound|outbound interface should not be mandatory
|
|
T4502: firewall: Add software flow offload using flowtable
|
|
while configuring dNAT|sNAT rule
|
|
|
|
T5518: Add basic MLD support
|
|
Cleanup nets for the smoketest load-balancing
Remove deleting container interfaces from default netns as those
interfaces leave inly in netns.
|

The following commands will enable nftables flowtable offload on interfaces eth0 eth1:
```
set firewall global-options flow-offload software interface <name>
set firewall global-options flow-offload hardware interface <name>
```
Generated nftables rules:
```
table inet vyos_offload {
flowtable VYOS_FLOWTABLE_software {
hook ingress priority filter - 1; devices = { eth0, eth1, eth2, eth3 };
counter
}
chain VYOS_OFFLOAD_software {
type filter hook forward priority filter - 1; policy accept;
ct state { established, related } meta l4proto { tcp, udp } flow add @VYOS_FLOWTABLE_software
}
}
```
Use this option to count packets and bytes for each offloaded flow:
```
set system conntrack flow-accounting
```
To verify a connection is offloaded, run
```
cat /proc/net/nf_conntrack|grep OFFLOAD
```
This PR follows firewalld's implementation: https://github.com/firewalld/firewalld/blob/e748b97787d685d0ca93f58e8d4292e87d3f0da6/src/firewall/core/nftables.py#L590
