Most broadband routers will give you access to do what is called "port forwarding" you will have to configure this to allow a remote connection to your internal PC. When you say that all computers on your lan have the same public IP address this is called your public ip, your computers on the LAN have private ip's. what you are going to do is this. for this example the public ip will be 216.190.123.190 and your computer on the local network will be 192.168.1.100. If you were going to have a remote desktop connection set up to your computer it would be set up like this.. the remote user would try to connect to 216.190.123.190 in their remote desktop software. your router will need to have the port for remote desktop 3389 point to your computer. so traffic will go to 216.190.123.190:3389, the router/firewall will then forward it onto your computer 192.168.1.100:3389. This creates a one to one relationship. only one port can be forwarded to one local pc. meaning if you have 5 computers only one of them can receive remote connections You have another remote option you can set up an incoming connnection in XP and 2000. It lets you connect one user remotely to a vpn connection. you can then access all computers / printers on the lan.
