From the following sections, choose the heading that best applies to your equipment
or networking configuration.
Network with Multiple Public IP Addresses
A Public IP address is visible on the Internet. (Most commonly found in business
environments.)
Recommended Procedure: If there is an available public IP address, simply enter the IP
address, subnet mask, and gateway into the applicable fields in the Network Settings
screen. If the network has a DHCP server, select the checkbox under the Network
Settings that says, "Automatically obtain IP address." (The network administrator will
be able to tell you whether or not the network has a DHCP server.)
Potential Issues: Some firewalls are configured in a way that could potentially restrict
H.323 data flow. Most current corporate firewalls are H.323 compliant. If this is the
case, configuring the firewall is accomplished by simply opening the necessary H.323
ports into the network:
Port 1720 (TCP)
Ports 15328 – 15333 (UDP & TCP)
If your particular firewall does not have this option, consult the firewall's documentation
on how to open specific ports needed for H.323 communications.
Broadband Modem and One PC
(This is the most common scenario found in a home or home office that currently has
one PC connected to its broadband modem.)
Recommended Procedure: Request from your ISP an additional public IP address.
With a second public IP address, the VideoPhone will be visible to the outside world
just as the existing PC. The ISP can either assign a static IP address or allow you to
dynamically request the IP address via DHCP. Follow the instructions in Broadband
Modem Only section, below, depending on what your ISP requires.
Because most broadband modems have only one Ethernet port, it will be necessary
to install a hub or switch between the modem and the rest of the network. Using an
Ethernet cable, connect the modem's Ethernet port to the applicable uplink port on
the hub. Once that is done, you can plug the PC and DVC-2000 VideoPhone into any
other available port.
