Allow an application go through an specific port in TMG

Hi people,

I'm having the following case:

I have an application which connects to internet (to a web service I suppose) through the TCP port 25601, this app is used by a few users inside my company. The thing is, I created an allow rule to this port, but when the users try to connect via the app, it fails and throw me the error: wsa_rws_error_access_denied.

The users can navigate on internet with restrictions but can access internet. If I run the APP on my computer which has full access to internet the firewall lets the app connect.



Here's my rule and what the logs says.

The Map APP TCP has the TCP 25601 port wich you can see in "Destination Port". 

Thanks in advanced.
