Port Redirection

[Nefarious]

I have two internet connections to an office, managed by separate routers. One has a dynamic IP address and one a static. The service provided on the static line is unreliable to say the least so the majority of the trafic goes through the dynamic line with the router set to be 192.168.0.1 and the static line to 192.168.0.2

A number of incomming connections are required including FTP, VPN and SSH. The VPN works fine, but the port redirection does not. I would not have thought that the IP address being other than .1 would have caused such a problem - am I missing something? Can you suggest a way around this?

I shall attempt to clarify. There are several inbound connections on the static address. The Billion router allows upto 5 VPN accounts to dial in which it assigns an IP address on the local network. The VPN functionality seems to be fine with the router set to 192.168.0.2.

The router also provides virtual server functions and intercepts inbound services on various ports and redirects them to different addresses on the local network. For example port 22 (SSH) is directed to 192.168.0.100. It is the virtual server functionality that seems to be unable to function at the moment.

I have no idea what Skidilliplop is suggesting. I don't have a remote site and am unsure how I could use dynamic DNS to allow remote users to access the server via SSH. Please could you explain further.
