Redirecting traffic to another server.

[kilburn]

I'm sorry, but what you're trying to achieve is -almost- impossible, by the nature of NAT and not as an ispcp limitation. There are only two possible ways:

1. Setup proxies for each service, that redirect traffic based on the destination domain or username (most of them doesn't allow "name based virtual hosting").

2. Setup your router's NAT table so some non-standard ports map to the second server. This way you would be able to connect through them (like YOUR.EXT.ERNAL.IP port 222 connects to 192.168.0.2 22, etc.)
