Question

Hello, I'm running an RUT 955  with  FW RUT9_R00.07.00 connected with Open VPN

I'm able to connect with ssh, but I get a disconnected after apx. 20 seconds. Keepalive settings on Putty didnt't help, logging in Putty doesn't tell something except "Event Log: Network error: Software caused connection abort" I've tried a Linux System too, with the same result. Ping is stable, ssh gets disconnected.

Is there some kind of whitelist, or extended ssh log on the RUT955 available? Troubleshoot didn't help.

Thank you!

Best regards!

Hello,

I am wondering if you would try to reconnect to SSH instantly, will it allow you to? Could you share your OpenVPN settings (blur out sensitive information)? Also, you can use logread command in SSH/CLI to review all logs.

Regards.

 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!
