OpenVPN and DNS

[John Abreau]

Has anyone gotten OpenVPN fully working? I've been trying to get it set 
up, and I can't seem to get DNS to work through the VPN tunnel.

Everything else seems to be working fine. When I ssh or point firefox to 
an IP address on the other side of the tunnel, it works okay, and when I 
put hosts on the other end into my client's /etc/hosts file it works 
fine. But when I try to point resolv.conf at the DNS server across the 
tunnel, lookups just fail.

I tried probing with nslookup and dig:

     nslookup azrael.us.zuken.com 10.1.4.29
     dig @10.1.4.29 azrael.us.zuken.com

and both just hang there and eventually timeout; they never reach the 
DNS server at 10.1.4.29. I can ping 10.1.4.29 just fine, and I can ssh 
to it; I just can't get DNS to respond from it. And if I ssh to a host 
on the other side of the tunnel, I get DNS from 10.1.4.29 just fine.

Any ideas what I might be missing?
