Routerboard catches all SSH traffic

Hi,
Has anybody got an idea of what is going on here?
I upgraded my routerboard to version 6.41.3 and since that upgrade every ssh session I try to do, when it has to pass the routerboard (so no, not an ssh session to the device itself) the routerboard catches the session and generates a public key error on my client pc.
It doesn’t matter if the session needs to travel from 1 vlan to another or that I want to connect to a device on the internet, as soon as it has to pass the routerboard, the routerboard itself answers to that connection attempt.
I already disabled the ssh management, but that doesn’t help.

I hope this behaviour sounds familiar to somebody and that it’s an easy fix… :slight_smile:

Thanks in advance for your help!
Kind regards,
Erwin.

Did you by any chance try to do something with dstnat? Forwarding ssh port for example?
