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

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

Also add IPv6 link local address support to auto generate a link-local address as on any other type of interface.

With recent versions of strongSwan and XFRM interface in VyOS 1.4 this is now possible.

There is no dict if exists only one record in the https://github.com/vyos/vyos-1x/blob/cefc7ce9bfcf7750700e73edbc21864fe8ab0bee/src/op_mode/show_nat_translations.py#L103-L110
So it can't parse correctly

Maybe it depends on the version of accel-ppp.

VTI is secretly IPIP, so it doesn't support IPv6. The real issue is that we don't support the IPv6 variant of VTI yet.

@Viacheslav There is already a set interfaces bridge brN igmp node. If the default option is enabled, I think set interfaces bridge brN igmp disable-snooping would sound better.
I prefer to have IGMP snooping disabled as the default option, since improper IGMP snooping causes issues while disabling IGMP snooping doesn't.

This seems to be an issue in 1.4 as well, I have the exact same symptoms, and removing the accept-protocol fixes the issue.

PR: https://github.com/vyos/vyos-1x/pull/1380

Implemented as: set service router-advert interface eth0 name-server-lifetime <value> which will be option A

PR https://github.com/vyos/vyos-1x/pull/1379 (without completion help)

Because with a rule like that I accept everything coming from nl from wan to lan, or I would need to add the source nl to every rule. That's why I did it with a deny not coming from nl on top, and then specific rules for the traffic that I want to accept.

If the default option is enabled or 1
Maybe it makes sense to create disable option like:

set interfaces bridge br0 ip disable-multicast-snooping

Did you try dns forwarding domain?
