I have set up a Router on my redhat box and the router and firewall seems to be working fine. I can ping the outside world from my freeBSD server so ip forwarding is ok
but when I try to ping a host name like google.com it can not resolve name. At first I thought the problem could be the firewall but I have checked that many times and it looks ok. does anybody have a clue what my next step should be.
Thanks

My guess...
You need to get the IP address of the DNS server of/from your ISP, and punch that into your DNS Host config. Also, check that your Gateway setting is pointing to the router (usually 192.168.x.x, where x is 0 or 1).
For example, my Linksys is sitting at 192.168.1.1, and my box is DHCP'd at 192.168.1.102 (I've got lots of stuff here). However, I'm using Charter cable, so this is what I've got set:
Lan IP: 192.168.1.102
Gateway: 192.168.1.1 (router)
DNS Pri server: 24.247.24.53 (bay.chartermi.net)
DNS Sec server: 24.247.15.53
Essentially, when you ping an address, it goes right there, but when you use google.com, it needs to find out what IP google is using from a "lookup" table - the Domain Name Server. So that one single location doesn't get nailed with billions of requests, they keep copies of it all over the place, so you can use your local ISP's copy, and speed things up a bit.
