Problems With Internal DNS

charlandg
I am working on an internal network with static, non-routable IP addresses.

Within this environment there is an internal DNS server that has a static, non-routable address and is forwarding to a DNS server (routable IP)that our ISP provides. The client PCs in the internal network point to the internal DNS server.

I am running Astaro 3.2.09 and using Masquerading to pass data through the firewall. I have not configured DNS proxy on the fire wall because I assume the use of Masquerading will pass the name searches from the internal DNS server through the firewall. (Is this assumption correct?)

As of now I am unable to browes to sites outside the firewall unless I set a rule in Astaro that allows 'Any' client and 'Any' service to 'Any' server but obviously this opens the firewall to everyone.

Can anyone see what I'm doing wrong here? Do I need to create a new 'Rule' to pass DNS queries through the firewall?

Any help would be appreciated.

Thanks.
