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.

Hi,

You could use Telnet to check if the TCP port 25601 is allowed.

Based on the deny log, the error message indicates that connection was denied by "ALL DENY" rule. Please double check the rule configurations.

Best Regards,

Joyce

Hi,

I would recommend that you have a look at your source and destination network. I recommend that you use for from internal to external instead of "All networks". I would guess that there's no routing rule that fits here.

Start with changing that and if that doesn't work, use the traffic simulator under the troubleshooting node to see where it goes wrong.
