apt-get oddness gutsy server on DMZ

[eyeroll]

Howdy,

I am having issues with running apt-get update - and all other apt functions for that matter. I have a recently installed Gutsy server that I am building and placed it in a DMZ.

When I run apt-get update all of my sources are "111 connection refused". I can ping internet based hosts - yahoo.com for exampple, and I have access in to the server via ssh.

I then put the server on my LN temporarily and apt-get update worked...

Any ideas why when the server is located on a DMZ subnet - going through the same firewall as the ALN - apt-get update fails ?

I am really confused by tis.

Thanks,
