Multiple network devices, 1 to ISP, other as DHCP to clients
 
I have two network devices installed on my Fedora system.

I am trying to use eth0 (a wireless USB device) to connect to my cable router for internet.

I am trying to use eth1 as my DHCP to my client workstations.

Prior to activating eth1, my internet was working like a charm. Now when eth1 is activated, i can get my client machines to successfully optain an IP address from DHCP, but neiter the clients or the server has internet access now.

When i try to hit a site from the server, it hangs on 'resolving host...', so something must be throwing my DNS off. Also, if I try ping the cable router (192.168.0.1), it times out.

ifconfig shows eth0 as 192.168.0.2, which is being automatically obtained from DHCP, and shows eth1 as 192.168.0.10, which is static.

Any help would be appreciated.

check your routes/gateway setup. be sure to resolve the internet connection on the server before checking with the clients.

What kind of router do you have? If it is a cable router that also assigns ip addresses, you may want to disable that and use a static ip for your dhcp server / wireless gateway computer. From your description, I am assuming that you are using your desktop Red Hat computer as a gateway because the other computers don't have wireless receivers. Is the gateway computer in the DMZ?
