Hi,
Running ASL 1.811
We have our two DNS servers behind the firewall, (both are Win2K boxes). We also run a couple of web servers behind the firewall. We are using a class C address for all machines, (no NAT).
I have the following rule in place:
ALL -> DNS -> ALL
But, if I type in the URL for any of our webservers, the name is not resolved. If I type in the IP address of the web server, the page loads fine. I tried this with all 5 of our different web sites.
If I activate the rule. ALL->ALL->ALL then domain names start to resolve and everything works great (but I dont have much of a firewall then). This is very repeatable error, turning the ALL filter on and off with turn off the name resolution like a light switch.
Can anyone shed any light on this, are there other filters I need to activate to get domain names to resolve correctly ?
Please help !
