InnoMedia iPBX Administrative Guide
7.5.3
Port Forwarding
This feature is only available at models iPBX-400F, and iPBX-404F
In addition to Telephony functionality, as an edge device, iPBX also plays the role of a voice firewall and
NAT to hide the LAN topology and LAN hosts. Port Forwarding is used to offer applications running on
network hosts which are behind iPBX to access Internet services. This section is to configure iPBX to
forward certain application ports to these particular LAN hosts.
