ISA Server, Non-Standard Ports, and External Website Access

Posted on 2008-11-05

I have a website that can be accessed from inside the network but not external to the network.  I'm not familiar with an IIS setting that restricts external website access, so I assume this is related to a firewall blocking the non-standard ports that the website is running under.  The network guy added a rule into ISA server from external to localhost with a custom protocol allowing inbound connections on these two non-standard ports.  Would there also need to be a rule for outbound connections on those ports?  What else, other than ISA server firewall settings could be preventing me to access the website from outside the network and referencing the external IP address?  Thanks!

    What the network guy has done is OK, no need to other rules it is better to keep you safe from outbound attacts
