Not supported with swanctl

Rewrite strongswan IPsec authentication to reflect structure
from swanctl.conf
The most important change is that more than one local/remote ID in the
same auth entry should be allowed
replace: 'ipsec site-to-site peer <tag> authentication pre-shared-secret xxx'
=> 'ipsec authentication psk <tag> secret xxx'
set vpn ipsec authentication psk <tag> id '192.0.2.1'
set vpn ipsec authentication psk <tag> id '192.0.2.2'
set vpn ipsec authentication psk <tag> secret 'xxx'
set vpn ipsec site-to-site peer <tag> authentication local-id '192.0.2.1'
set vpn ipsec site-to-site peer <tag> authentication mode 'pre-shared-secret'
set vpn ipsec site-to-site peer <tag> authentication remote-id '192.0.2.2'
Add template filter for Jinja2 'generate_uuid4'
|
|
If IPsec "peer <tag> authentication remote-id" is not set
it should be "%any" by default
https://docs.strongswan.org/docs/5.9/swanctl/swanctlConf.html#_connections_conn_remote
Set XML default value in use it in the python vpn_ipsec.py script
|
|
Remote TS for transport mode GRE must be remote-address and
not peer name
|
|
This enabled users to also use 2FA/MFA authentication with a radius backend as
there is enough time to enter the second factor.

Commit bd4588827b ("ipsec: T4118: Change vpn ipsec syntax for IKE ESP and peer")
changed the CLI syntax of ipsec. This resulted in a node not renamed in the
op-mode generator when generating IKEv2 IPSec iOS configuration profiles.
|
|
The "authentication id" option for road-warriors did not get migrated to
the new local-id CLI node. This has been fixed.

ipsec: T4118: Change vpn ipsec syntax for IKE ESP and peer
|
|
Migration and Change boolean nodes "enable/disable" to
disable-xxxx, enable-xxxx and just xxx for VPN IPsec
configurations
- IKE changes:
- replace 'ipsec ike-group <tag> mobike disable'
=> 'ipsec ike-group <tag> disable-mobike'
- replace 'ipsec ike-group <tag> ikev2-reauth yes|no'
=> 'ipsec ike-group <tag> ikev2-reauth'
- ESP changes:
- replace 'ipsec esp-group <tag> compression enable'
=> 'ipsec esp-group <tag> compression'
- PEER changes:
- replace: 'peer <tag> id xxx'
=> 'peer <tag> local-id xxx'
- replace: 'peer <tag> force-encapsulation enable'
=> 'peer <tag> force-udp-encapsulation'
- add option: 'peer <tag> remote-address x.x.x.x'
Add 'peer <name> remote-address <name>' via migration script

Fix template for configuration DMVPN IKE profile
dead-peer-detection delay and dead-peer-detecion timeout options

Set default passtrough list to None to prevent unexpected policy
for peers with not overplapped local and remote prefixes

close-action parameter is missing in the swanctl.conf file

ipsec: T1856: Ability to set SA life bytes and packets
|
|
set vpn ipsec site-to-site peer 192.0.2.14 connection-type none
|

set vpn ipsec esp-group grp-ESP life-bytes '100000'
set vpn ipsec esp-group grp-ESP life-packets '2000000'

Ability to set Cisco FlexVPN vendor ID payload:
charon.cisco_flexvpn
charon.install_virtual_ip_on
swanctl.connections.<conn>.vips = x.x.x.x, z.z.z.z
set vpn ipsec options flexvpn
set vpn ipsec options virtual-ip
set vpn ipsec options interface tunX
set vpn ipsec site-to-site peer x.x.x.x virtual-address x.x.x.x

Add priority for policy based IPSec VPN tunnels
If 2 tunnels have the same pair of local and remote traffic
selectors (prefixes) it allows to set more preforable install
policy from required peer
The lowest priority is more preforable
|
|
Peer name must not contain dots and colons, otherwise
swanct can't generate correct configuration for swanctl.conf
This is used in connection names and child SA names
Add filter 'dot_colon_to_dash' which replace dots and colons
|
|
|
|
|
|
The key defaults to 0 and will match any policies which similarly do not have
a lookup key configuration. This means that a vti0 named interface will pull in
all traffic and others will stop working. Thus we simply shift the key by one
to also support a vti0 interface.
|
|
Manually set peer id and use-x509-id are mutually exclusive!

Restore "default" behavior from ipsec.conf

IKE lifetime is life_time, and ESP lifetime is rekey_time.
|
|
Commit 7a873eb6 ("ipsec: T3764: bugfix missing IKE and ESP lifetime values")
re-added the lost in translation IKE/ESP rekey values. But it did not specify
the unit, which is s(econd).
|
|
During the migration the IKE and ESP key/re-key lifetime settings got lost in
translation. This is now fixed and the values/defaults correspond to VyOS 1.3.

As this is only related to remote-access, keeping it under "options" simply
feels wrong.

generate ipsec mac-ios-profile <connection> remote <ip|fqdn>
will generate a matching IPSec profile which can be loaded on an iOS device.

Connection uniqueness policy to enforce. To avoid multiple connections from the
same user, a uniqueness policy can be enforced.
* never: never enforce such a policy, even if a peer included INITIAL_CONTACT
notification
* keep: reject new connection attempts if the same user already has an active
connection
* replace: delete any existing connection if a new one for the same user gets
established
To compare connections for uniqueness, the remote IKE identity is used. If EAP
or XAuth authentication is involved, the EAP-Identity or XAuth username is used
to enforce the uniqueness policy instead.

Remote access IP pools can now be defined at a global level and referenced
in IPSec remote-access connections. To defined a pool use:
set vpn ipsec remote-access pool global-ipv4 name-server '172.16.1.1'
set vpn ipsec remote-access pool global-ipv4 prefix '192.168.0.0/24'
set vpn ipsec remote-access pool global-ipv6 name-server '2001:db8::1'
set vpn ipsec remote-access pool global-ipv6 prefix '2001:db8:1000::/64'
A connection can then reference the pool:
set vpn ipsec remote-access connection foo pool 'global-ipv4'
set vpn ipsec remote-access connection foo pool 'global-ipv6'

... this enables a dual-stack IKEv2 VPN deployment.

update to use PKI.
|
|
|
|
- Adds client/server authentication methods.
- Adds basic verification to remote-access.
- Adds DHCP pool and options to remote-access.
- Cleanup unused PKI files.

Used by both site2site and remote-access/road-warrior VPN connections.
