Changing Ip Parameters; Proxyserver - Multitech MVP200 User Giude

Chapter 4 - MultiVOIP Software

Changing IP Parameters

The IP Setup dialog box establishes the IP addressing for the local Ethernet LAN, defines the Internet
gateway address, and for a remote MultiVOIP the global-to-local IP address translation is defined on
the Proxy Setup tab. The IP Setup dialog box is accessed by clicking IP on the MultiVOIP 200 Setup
menu.
When the IP Setup dialog box displays, the IP address of your MultiVOIP displays with its IP Mask.
The Gateway Address is the IP address of the device connected to the Internet.

ProxyServer

The Proxy Setup tab is used when a ProxyServer is used to connect the LAN to the Internet.
If a ProxyServer is used in a MultiVOIP network, an address translation takes place within the
ProxyServer to direct the phone call to the correct MultiVOIP.
When a MultiVOIP's connection to the Internet is through a ProxyServer, the WAN port on the
ProxyServer must have a static registered IP address. Remote MultiVOIPs will only be able to
access a MultiVOIP located behind a ProxyServer at the static IP address. This static IP address will
be used in the Phone Directory Database when assigning directory numbers to this MultiVOIP.
The Global IP Address box must contain the static IP address of the WAN port of the ProxyServer.
The Local IP Address box must contain the local IP address of the MultiVOIP. In this case the local
IP address is not used in the Phone Directory Database. There must be a unique static IP address
on the Wan side of the proxy server for each MultiVOIP located behind the proxy server.
