BCM 400 behind firewall

[PressAltF4]

This is my situation: I have the BCM ~only~ connected to the local lan, with the firewall pointing port requests to the BCM (7000, 28000-28511, 51000-51200).

The IP phones work internaly, but from outside when I'm trying to connect any IP (soft or hard) on the display I got this message: "Connection established" Reinitializing ... nothing else happend.

Can't be done, unless your firewall supports "cone nat". You'll want to use a VPN for this application.
