Hi Robert, There is a system policy that allows the ISA firewall to access DNS from the local host network to all networks, so there's no reason to add more rules for that. If you need to allow other hosts to access the DNS server, then you'll need to add rules to support those connections. For example, if you want Internal network hosts to connect to the DNS server, then you'll need to bind the DNS to the Internal address, and then create a rule allowing Internal to Local Host for the DNS protocol.

I specified "Allow" - protocols :"DNS Server" and "DNS" - From "DNS TEST" (machine name) ip:XXX.XXX.XXX.XXX - To "External" (whole internet) This rule is enough so that the test DNS server can access the internet and query forwarders or no? If I do not specify any users in the users section of the rule how will this react? Where can I find more related info to ISA 2K4 please? regards, Robert Abela This mail was checked for malicious code and viruses by GFI MailSecurity.
