How to identify the applications that are locked to a specific computer?

[arvelaiz]

Hello everyone. I just installed the latest version of Sense PF as a transparent proxy, install the pack Squid to filter web content.
The problem is that there is a server application called the PF Sense EdiWebPrint locks it and prevents proper operation.

I created both the filter rule as a rule in the firewall to that server to pass freely without restrictions.
But by placing the gateway PF Sense, this fails.

That I can use to see what happens with applications that makes that application and it is denied …

The configuration of the PF Sense is a NETWORK LAN and two WAN networks, configured as load balancing

Thanks for all your help.
