Hi Felipe,
You would want to turn on Manual Outbound NAT (Firewall: NAT: Outbound) and in your outbound NAT rule, check the "Static-port" checkbox.

Hi Giles, here we go.
I'm not using ISDN, so I just configured my internal IP in LAN settings with my internal DNS and the public google DNS. Also I have configured the advanced settings with selecting "system is behind a nat" with my external IP.

As a could see searching on the internet, PfSense rewrites non common TCP and UDP ports in a NAT to protect against atacks, but Polycom uses this ports for audio and video.

        Hi guys, have anyone had a problem with Polycom ViewStation
        behind a PfSense NAT.
        I have setup a NAT 1:1 to my Polycom ViewStation and no
        restrictions in any ports.
        The problem is that, when I make or receive a call, it enters
        in the room but the screen gets blue and there is no sound.
        Testing Polycom conected directly in the router without
        Pfsense, everything works fine.

        Any idea about this problem?
