Hello, the ssh service i recommend accept define IP:port in command that we can set untruest interface to other port better than only one port, in LAN port we keeping the default Port:22.
eg: publice_IP port 5555
LAN_IP port 22
similar command like this: set service ssh listen-address x.x.x.x port xx
Sorry, please ignore my first reply on re-reading your post I understand what you’re asking.
This is possible I believe with openssh so I guess it would be possible to add to VyOS.
I have moved this post to the Feature Request section of the forum.
