hey,
you could connect your server directly to you isp, throw another NIC in that server which is then connected to your router/hub/whater. Lastly you'll need to do internet connection sharing on your NIC that is connected to your ISP. That is the ghetto way around it but it is probably the easiest to set up. Oh, and I think you need win2k/orXP for this to work.
