Road Runner && DNS Problems

[Chris Hoover <choover@bellsouth.net>]

I'm having some problems with my Road Runner Cable modem and getting the DNS to properly work.  Hopefully, someone can help me get this straight.

Here is my current setup:

internet
  |
  |
debian-wall (Firewall box)
  | 
  |
  Hub---(debian-server - DNS server for the network)
  |
  |
  (Multiple PC's)

The problem I'm having is that I'm unable to access pop/smtp/nntp servers that Road runner provides from anywhere on my network except debian-wall.  Road Runner is using dhcp to assign me the ip-addr and I have that working.  I also have ipmasq working so all of my networked machines can get in and out to the internet.

I did directly connect my windows box to the cable modem and looked at the dhcp address.  I then added what it said where the dns servers to the named.conf file on debian-server, but still no help.

Can someone help me resolve this problem?  

I've come up with a couple possible solutions:

1.  Run DNS on debian-wall.  This is possible, but I really don't want any extranous programs running on that box to help prevent holes as I setup my firewall.

2.  Get debian-wall to update the dns on debian-server.  I have no idea if this is even possible, much less how to implement it.

Other/better ideas?

Thanks for any and all help,
