Configuring Router Port Forwarding - Polycom V500 Administrator's Manual

Configuring Router Port Forwarding

To make video calls with your V500 system when you have a router, you must
open and assign ports in the firewall. This section describes how to do that
with some common routers from NETGEAR®, Linksys®, and D-Link®. Most
other routers require similar procedures.
Before you can change your router configuration, you must know:
• The IP address of your router, which you can find in your router's
documentation. (Many routers use the default address 192.168.1.1.)
• Your router's administrator name and password, which you can find in
your router's documentation. (Many routers use the default user name
admin and the password blank or password.)
• The IP address that has been assigned to your system if you're using
DHCP, which you can find on the LAN Properties screen. (See
Configuring LAN Properties
With any router, you must open the ports listed here:
