[olug] Re: Wireless Help

Sam, thanks for the response, but both of those are set correctly. After 
much research I'm still at a standstill. It appears I'm still struggling 
with routing. Again, I'm trying to get a windows laptop to talk to a RH 7.3 
box, and then to the rest of my network. The wireless stuff is working 
great. I can ping the RH wi-fi interface (10.0.1.1) from the laptop and I 
can also ping the wired interface (10.0.0.5) from the laptop, but nothing 
beyond that. So, I'm assuming I have a routing issue on the RH box. I'm 
missing something obvious, but I don't know what. Here are the details. Any 
ideas?   Thanks,
