can't resolve names, ipchains or dns problem

[Nick <daye149@pacbell.net>]

Hi list,

I have an internal network setup behind linux on a single static IP
I am having problem reolving names but can ping IP's numericaly.

I set up dhcp to allocate 192.168.1.0/24 throught the internal network
Then I setup ipchains very basic, just to get it all going

ipchains -P forward DENY
ipchains -A forward -s 192.168.1.0/24 -j MASQ

kernel is set to forward, echo "1" > /proc/sys/net/ipv4/ip_forward

So I can ping from an internal machine to any global IP address, but when it 
comes to ping www.yahoo.com, get a bad host message.

Using 192.168.1.1 as gateway for internal machines
looked at /etc/resolv.conf,  looks ok
/etc/hosts
/etc/network/interfaces all good too

route tables look ok
have 255.255.255.255 line for dhcp windozs
default gateway ok

I can ping domain names and ip address from the linux firewall.
Just doesn't seem to want to forward those requests for the internal network 


HELP!!!
