Internet and Intranet Calling with Polycom PVX 8.0.1
If your network is behind a fully aware H.323 firewall, you do not have to configure port
forwarding. Your firewall can detect H.323 video traffic and open ports as necessary. Please
contact your network administrator and refer to Configuring Your Connection from the PVX
Application.
Using a router that does not support Universal Plug and Play (UPnP)
If your router supports Universal Plug and Play, please continue to the next section. If your
router does not support Universal Plug and Play, proceed to the section Configuring Your
Router's Port Forwarding.
Using a router that supports Universal Plug and Play (UPnP)
Many new routers use UPnP technology that automatically detects network devices,
assigns IP adresses, and enables communication. If your router has UPnP capability, you
do not have to manually configure router ports to open for PVX traffic. PVX 8.0.1 can use
UPnP to automatically open the ports required during your call and close the ports after
use.
If your network security policies prohibit you from using UPnP, you can manually
configure port forwarding. Refer to the next section, Configuring Your Router's Port
Forwarding.
To use UPnP port forwarding:
1. In PVX, click Setup > Network to open the Network tab.
2. On the Network Setup page, click the Connection tab.
3. Select Behind a NAT/firewall.
4. Click Apply.
5. Click the Ports tab.
6. Select Use UPnP port forwarding.
