Until recently I have had 3 computers sharing a fixed IP address Satellite internet connection using a Linksys WRT54GSv4 router. Each computer had a unique IP, 192.168.1.1xx, and port forwarded in the router. The router is assigned IP 192.168.1.1, and the Satellite terminal (IPX5100) is assigned IP 192.168.0.1. ADSL service has just become available in the area so I ordered it and the installers brought the equipment and were only able to set it up to work on a single computer as they did not know how to get it to work through the router. I wanted to have a fixed IP address, but had to settle for a dynamic IP address. Looking at what they did I see that they have set the one computer's Internet Protocol (TCP/IP) Properties to "Obtain an IP address automatically. If I understand correctly, this has nothing to do with my IP used over the Internet, but only the IP used between the computer and the ADSL modem. In order to access the ADSL modem setup, I found I had to enter 192.168.1.1 which is also my router IP, and I assume that would cause a conflict. I would like to have the ability to leave all computers connected to the router as previously and be able to connect the router to either the ADSL box or the Satellite box with nothing more than a cable change. I'm not sure what all needs to be done in the ADSL box to accomplish this, or if there might be some changes needed to be done in the router as well. Has anyone ever succeeded in doing this and able to give advice? I'm not very knowledgeable at all in this area and would appreciate any help.
