Clients connecting to server showing as pfSense IP?

[tuffcalc]

I have a weird issue.  I have a PBX that phones (local) connect to.  The PBX server is showing the clients connected, but their IP address is the pfSense IP.  Everything works fine but it causes problems for my fail2ban settings.

Any idea what could be causing this?

Thanks
