Feature backport: https://github.com/vyos/vyos-1x/pull/1400

@dsummers I strongly believe we should not publish bleeding edge HEAD revisions and stick bleeding edge releases only.

After doing some research, it appears this is a known bug in PowerDNS Recursor 4.7 (amazing to me).

This feature would be very helpfull for hairpin nat as we can see from the mentions.
Might also be helpfull for ipv6 as well.
I am aware its a different product but edgeos from ubiquiti does something like this (looks to be a managed address group that populates dynamically) for nat and fw:

Confirmed working on "current" branch.

Is anyone else seeing this same problem? It is keeping me from being able to use VyOS in an IPv6-only environment.

OK, I just noticed the merge to "current" branch.

I'd be glad to help test it, but I checked the repos and didn't see where it got merged in?

I think there's still a problem possible with /var/log/messages handling:

Confirmed issue, seems to be a problem in rsyslog/logrotate. Possibly related to T4250

@Viacheslav I tested your fix in my environment. The inbound filtering worked as expected after the fix. However it did not work correctly for the case we where we want both inbound and outbound firewalls on a single vrf member interface (or any case that has more than 2 directions on the same interface).

table ip filter {
	chain VYOS_FW_LOCAL {
		type filter hook input priority filter; policy accept;
		oifname "ONE" counter packets 63 bytes 6024 jump NAME_FOO # <<< Problem here, oifname should be eth0, not vrf name
		iifname "ONE" counter packets 63 bytes 6024 jump NAME_FOO
		jump VYOS_POST_FW
	}
...
	chain NAME_FOO {
		ip saddr 8.8.8.8 counter packets 79 bytes 6636 drop comment "FOO-10"
		counter packets 3 bytes 984 return comment "FOO default-action accept"
	}

@a.apostoliuk Could you create PR for 1.3?

Pull request for VyOS 1.4

I see that the pull request was accepted. I just tested it with the latest rolling and it seems to work as expected.
Thanks a lot!

Confirmed that issue is resolved.

I dug a little deeper, it appears that calling 2 http APIs in parallel results in vyos-http-api library crash.

Sorry just to clarify these are mostly web domains, not DCs, so there is no DNS running on them just HTTP.

I wanted to ask you guys if this is an appropriate change to make. Considering it's on BGP, it's going to be a change in a crucial part but I think this one is probably a good one to make just to reduce ambiguity.

Or probably better:

NTP listen option not only supports IPv4/IPv6 addresses but also interface names.

Oh, if you are asking for an example of what the VyOS config setting would look like?

I've been manually adding TAYGA to VyOS (See T160) for my NAT64 capability.

@dsummers Could you provide an example of VyOS configuration and an example of what you add?

Yes, I spent quite some time trying to replicate your findings until I noticed that you used if commit_in_progress, so the truth value of a defined object that isn't None or False was trivially true.

Bug of testing
I tested commit_in_progress instead of commit_in_progress()

@marekm Did you set a proper listen to address for it?

set system ntp listen-address x.x.x.x

Is there any further testing needed by me or someone else will do that?

I tested on VyOS 1.4-rolling-202207030217. The bug was resolved.

I already tested the PR before submitting:
