Is there not a problem with this? I'm not completely sure about this, but access to the server from the internet, if the server has a public IP address, will not happen. WWW requests for example will be directed to the router not the server. Packets with public IP addresses will not traverse the internet. Or is it possible to configure a router to forward all packets for it's IP address to another machine for processing? The connection between the router and the server is considered to be a subnet so will require an IP address space which will be different from the internal network. However this connection will need real world side IP addresses for the real world to connect to the server. Or am I wrong?

If your new connexion provides an automatic IP address ( or you have one hard-coded in) for the real world side, set up a small Linux box to act as a masquerade/firewall between your internal network (using the standard 192.168 series of IPs presumably) and the outside. You'll need a more substantial RAM/CPU spec to run a proxy (which saves the need to masquerade). Masquerading will need a new kernel build to allow forwarding etc. and to build the appropriate masquerading modules.
