Hey @n.fort yes I did test it per my comment on Jan 23rd. It's fine just different in that type used to be a name and now it's an integer with a separate option of type-name. It's fine was just noting the difference compared to previous versions.
Thanks for checking!

@n.fort I just built a fresh image and tested. The first thing I noticed is that icmpv6 now only accepts integers while previously it accepted names. I'm assuming this is a purposeful design change where users now have to set type-name instead.
The any option has been removed, which I suspect is OK as you'd simply leave it unset if you want to accept all icmp types.
Overall this should eliminate the user confusion so I think it's a good change.

Confirmed, I just built a new image using 1.4-rolling-202201212148 and I can no longer reproduce the issue.

@Viacheslav this is great. I hope to get around to testing it this week.

Thanks @jestabro this seems like a good place to start learning VyOS internals, will give it a go when I have some off time and submit a pull request.

@jack9603301 I tried building jool into the VyOS image but because their deb packages uses DKMS which is not compatible with VyOS so somebody has to create a VyOS specific deb package.

I'm thinking about trying to run either tayga or jool as a docker container inside of VyOS. Has anyone tried something like this? If I wrote a guide on how to do this I wonder if it would be an OK temporary solution until it's integrated into VyOS.

ddclient version 3.8.2 is currently include with VyOS which is 2 versions behind. Latest is 3.9.0 which has the required fixes.
