My modem is the Siemens Gigaset. I didn't find any version or release number on the case nor in the documentation. The documentation says that the address of the modem is 192.168.1.1. Actually, if I give "ifconfig eth0 192.168.1.2", I can even look at modem status and statistics accessing the modem internal web server with Mozilla. Just like you, I didn't change anything by hands, I only used "system-config-network". I admit I made some test playing with DNS, route, and such, but unfortunately I cannot backtrack them any longer. My situation is different from yours, in that I have just the interface to the Internet (eth0). But that's puzzling me, just the relation between eth0 and ppp0: how they are related? Can I change eth0 address without affecting ppp0, or must I set it just in one way? And what is that way? I'll be back tomorrow with the output you asked for. Many thanks. -- Andrea Giuliano, Ph. D.
