You're right - the static routes were overkill. I have since removed them, but for some reason I am still unable to route between the two networks. Indeed I have set my router as the default gateway for my client machines using the 192.168.1.1 address that they can contact it on. When a client machine tries to ping a 10.1.1.0 address, I can see via Ethereal that the request goes to my router. I just still stumped as to why it won't forward the traffic on to the proper host! Being somewhat green on Linux administration, I even went to the bookstore last night to check out a Red Hat admin book. It seems to tell me pretty much what you kind folks have already told me. Hmmm... when I figure this out, I know it's going to be something I'll want to slap myself over. ;-) -Ian helmut djurkin wrote: > On Tue, 2002-04-09 at 15:44, Ian Zapczynski wrote: > > Hello all. > > > > I am a Sun administrator needing to get a router set up on Red Hat 6.2. > > I am simply trying to join two private networks, 192.168.0.0 and > > 10.1.1.0.
