Our LAN contains a server running openSuse 10.2 which was setup by someone else. When the machine was installed, our router had various port forwards set up to forward amongst others, ports 22, 80 and 443 to the Linux system. We have recently changed our router and whilst I can set up port forwards to any number of Windows machines on the Lan, the port forwards to the Linux machine are no longer accepted. Just to stress, the system worked perfectly with the previous router, I foolishly thought it was just a case of swopping routers and setting up the port forwarding on the router itsself.
I only have a working knowledge of Linux and because port 22 was used for SSH sesssions (via PUTTY), I am now stuck as I don't have remote access to the Linux system so a router based fix would be ideal. (If not I'll have to go onto site, not a major bind, just inconvenient.)
