Network Connection
Although connecting any networked device can be a confusing task,
we at Polycom are all for simplifying this process for you as much as
possible. When you start the ViaVideo application for the first time,
ViaVideo’s setup wizard leads you through a series of configuration
steps that set up ViaVideo’s network connection configuration
settings so you can begin using ViaVideo immediately.
If you need to change your network connection, or are using
ViaVideo in more than one network environment, you may need to
change your network configuration settings. This is best
accomplished by having your network administrator perform these
tasks for you.
If you don’t have a network administrator to take care of the
configuration for you, we’ve got you covered. Read the information
in this document and you will be ready to go in no time.
If you are a network administrator, go ahead and read the document
anyway. Your secret’s safe with us!
This document contains the following sections:
•Pick Your Connection Type (page 7)
•Configure Your Connection (page 9)
•What’s a Firewall? (page 17)
•What’s a DMZ? (page 19)
•What’s a NAT? (page 19)
•Multiple IP Addresses (page 21)
•Network Configuration Screens (page 23).
Pick Your Connection Type
As simple as we can make it - just pick out your connection type from
those shown below, perform the tasks in the appropriate section,
and you’re ready to communicate ViaVideo!
