I've seen DSL modems with 2 modes of behavior: * bridge mode where they simply translate DSL/Ethernet bits which is what you want if you supply the router * NAT/router mode where the modem assumes router/firewall duties I don't know if the cable modems offer similar capabilities. The DSL mode was controlled by the phone company and set by tech-support. I was helping a friend install a wireless router and was lucky to encounter a phone company tech support person who knew what she was doing. Perhaps your cable modem switched from bridge mode to router mode when the customer router was removed. > So it's up and running despite the weirdness that the Linksys router > was displaying. > > -Alex -- Lloyd Kvam Venix Corp DLSLUG/GNHLUG library http://dlslug.org/library.html http://www.librarything.com/catalog/dlslug http://www.librarything.com/rsshtml/recent/dlslug http://www.librarything.com/rss/recent/dlslug _______________________________________________ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
