Default firewall blocks apt-get?

When I activate default firewall in ISPConfig3 I got following connection errors when using apt-get update:

Err stable Release.gpg
  Could not resolve ''
Err stable/updates Release.gpg
  Could not resolve ''
Err stable Release.gpg
  Could not resolve ''
Reading package lists... Done
When I ping domains it also didn't work, but when I ping IP it works... so I think this could be related with server dns...

The issue is that when I deactivate the ispconfig firewall all works!

This server is a openvz vps, debian 5 with following firewall config:

Open TCP ports: 20,21,222,25,53,80,110,143,443,3306,8080,10000
Open UDP ports: 53,3306
