I'm running Apache Web Server on Windows 2000 as a test machine. I'm using Simple DNS for the DNS services. The test server works perfectly until I try using a firewall such as ZoneAlarm or BlackICE. I'm unable to connect to my URL when using the firewall. I have opened port 80 (HTTP) and 53 (DNS). What other ports need to be open to access the domain?

Thanks in advance.

Disregard. Problem solved.
