Dear Jestabro,
i built an updated docker image and a new ISO, i do confirm now IPv6 is working correctly.

PR: https://github.com/vyos/vyos-build/pull/343

Ok, if we merge the patch (backported to frr v8.5), this task can be close.

I think the only solution is to use network namespaces
https://docs.strongswan.org/docs/5.9/howtos/nameSpaces.html

Usernames usually take the following format: abc-1234-12
Passwords are a combination of alphanumeric characters.

Do you know how to tell Linux to use nameservers within a VRF?
What you mean IPSec/OpenVPN "punch a tunnel through a VRF" ? So the underlay should run via a VRF? source-interface binding does not work?

Thanks for opening the task; note that Viacheslav had opened
https://vyos.dev/T5185
as well, and the updates on the now fixed issue can be found there. This task can be merged into that one and closed.

Merged and repos updated, so this will be in the next nightly build. Note that for a local build, one will need an updated Docker image for the update to vyos1x-config.

This is a simple bug in the recently introduced configtree node name comparison function; fixed and should be in next rolling.

Do you have users/passwords with specsymbols or not utf-8 or some ascii symbols?

hmmm very strange.... here is my configuration (IP addresses removed):

Could you provide l2tp configuration? show conf com | match l2tp
I cannot reproduce it

@Viacheslav It hangs for a while and then eventually the following output:

@joshua.hanley Could you provide the output of the next command?

Two cents from the fields. It will be nice to see vrf aware cg-nat solution, when subscribers from a number of "inside" vrfs NAT'ed into one outside vrf. Of course if that's possible.

Test case above produces:
