Because they are not using modem in bridge mode and most routers default to WAN DHCP. I never refer to a DSL modem as nor use it as a router.
line -> liveip -> wan ppoe client -> modem -> nat -> lan dhcp server -> 192.168.0.x -> wan dhcp client -> router -> nat-> lan 10.0.0.x static -> switch -> multiple clients So from the router standpoint it's talking to a 192.168.0.x network on a dynamic IP NOT the live IP it should be seeing if you were on in bridge mode, on a cable modem or otherwise connected directly to internet.

Not sure if that was configured or if the router just grabbed what it was given by the modem. > fp > > At 10:56 AM 10/10/2007, DHSinclair Poked the stick with: >> Thanks Richard, >> Yes, I plan to play this one out by the learning I got from this List back in 99/00 >> when setting up the 1st go-round.
