You still have to tell your internal computer how to do DNS. For me, it's as
simple as setting resolv.conf to the nameserver address 4.2.2.1 on the
internal machine. Also, your firewall must have something along the lines of
echo 1 > /proc/sys/net/ipv4/ip_forward in your rules...for me, this works
because I'm using a 2.2.x kernel. I don't know if it would look like this in
2.4.x kernels.
