To get my LinkSys setup with Suse 8.2 (and prior) to work, I had to put in
my ISP DNS server IP addresses, not the IP address of the gateway. I guess
my firewall/router does not forward these lookups? I don't know if it
should, or if there is a setup option. I found these IP addresses by
connecting my web server to my gateway (admin login) and one of the panels
listed the DHCP address my ISP assigned to me (I don't need that for
anything, unless someone else wants to "find" me), and it also listed 2
DNS nameserver IP addresses. Try plugging those into /etc/resolv.conf
Oh, another thing, but pretty obvious. I notice you are using 192.168.0.x
for your subnet addressing (like I did). I had some trouble reprogramming
the LinkSys to use 192.168.0.1 instead of its default 192.168.1.1, and I
had to "fight with it a bit" (can't remember the exact details).
