Thats clear, I jsut didnt think that the router I dial into has to become the default route, I thought since the .65 was the gateay it had to show up in my routeing table. Now that I know that things should be easier now. > If you sit on machine 10.0.0.2 on your ether, and let's assume for a > moment the 10.x.x.x network were routed from the Internet, then the > picture would be a little different.

But then `your box' would have to be setup as a gateway to properly route the packests then...would it not? > From the man page, but on FreeBSD, not on AIX. :) (AIX's man page > describes AIX's netstat program.) > I know, just wanted to see if it would give any more info about the program. > Both routing tables are basically identical.

The routing itself is identical. Ok then, that basically answers what I needed to know. Ive archived your message for future reference. thanks much. I hope I can get this to work now. Keith
