I'm helping a business setup their firewall rules and want feedback on what a typical set of outbound TCP ports to open.
I hoping that people could also take a look at this screen shot of our config and provide feedback. I will be turning off WAN Management once I have it all set. The ports 135, 1225, and 443 are for our Hosted Exchange Solution. Do I need #3 for file sharing? Not sure if I need #9 DNS.
How do I upload the screenshot?
