Hi,

as you utilize a custom build with no clear indicator from which version the sources are, please try one of the recent rolling images from: https://downloads.vyos.io/?dir=rolling/current/amd64

Hi,

The build was done following this method
https://docs.vyos.io/en/latest/contributing/build-vyos.html

The crux ( latest LTS release) was built.

Its not crux.
It seems rolling version. “Release Train: equuleus”

In any case you can try this option:

set system sysctl custom net.ipv6.conf.all.disable_ipv6 value 1
commit

Hi @admin0,

unfortunately not - you have mixed the crux and equuleus branch. Which can be indicated by the “release train” shown in show version output.

Please try with our official rolling releases instead, so if its a bug we can track and fix it.
