Hello VykintasKuzma,
thank you for your help and imidiate reply I've configured the RUT955 in our local network (backup WAN - with Eth) without the use of the mobile wan. I've tried it now with the mobile wan connection and got a stable ssh via OpenVPN.
I've configured the RUT955 with the old firmware the same way and didn't have problems with the ssh, but as long they will work this way that is fine.
Problem solved, thank you!
Gerhard
