BT Office Communicator and Microsoft ISA Server 2000

[Steadfast]

We are unable to connect with the BT Office Communicator through our server which runs ISA Server 2000 as a proxy server. We apparently need to open port 5060 on the server. Can anyone tell us how to do this? I have searched the internet for possible solutions and it seems to be a common problem for servers running ISA server.

Must have missed this one when it got posted, I'm more familiar with ISA 2004 but anyway if your still having the problem or anyone else is try this.

1.      In ISA Management, right-click your server, and then click Properties.
2.      Click to expand Access Policy.
3.      Right-click Protocol Rules, and then click New.
4.      Create a protocol rule that applies to the specific protocol that you want to allow (such as HTTP) or click All Protocols.
5.      Select the schedule for this protocol rule.
6.      Click Specific Computers (client address sets) as the client type to which this rule should apply.
7.      Create a client address set or use an existing one that contains the clients to which you want to grant access.
8.      Click Next, and then click Finish.

Its possible it could be a modem/router problem also unless the servers in the DMZ or the routers acting in bridging mode.

Anyway try here to test the port forwarding (from the computer its forwarded to) http://www.t1shopper.com/tools/port-scanner/ & here http://nmap-online.com/

EDIT: I really hate editing posts, this forum just doesn't seem to like Firefox though.
