Chapter 2. Overview of the Installation

Quick guide to 3Com VCX IP Telecommuting Module installation

3Com VCX IP Telecommuting Module is easy to install:

•Select an IP address for the Telecommuting Module on your network.

•The network interfaces are marked with 1 and 2. These numbers correspond to the physical interfaces eth0 and eth1 respectively, the latter which should be use in the installation program.

•Plug in the power cord and turn on the Telecommuting Module.

•Wait while the Telecommuting Module boots up.

•Connect the network cables to the network interfaces.

•Find out the MAC address of the Telecommuting Module’s Network Interface 1 (printed on the Telecommuting Module label).

•Add a static entry in your local ARP table consisting of the Telecommuting Module’s MAC address and the IP address it should have on Network Interface 1.

This is how to add a static ARP entry if you use a Windows computer: Run the command command (or cmd).

In the Command window, enter the command arp -sipaddress macaddress where ipaddress is the new IP address for Network Interface 1, and macaddress is the MAC address printed on the Telecommuting Module, but with all colons (:) replaced with dashes (-).

•Ping this IP address to give the Telecommuting Module its new IP address. You should receive a ping reply if the address distribution was successful.

•Direct your web browser to the IP address of the Telecommuting Module. You will be prompted to set a password for the Telecommuting Module admin user.

•Now you can see the top page of 3Com VCX IP Telecommuting Module. Click on the Telecommuting Module Type link and select the configuration for your Telecommuting Module. The types are described on the web page.

•Go to the Network Interface 1 page and enter the necessary configuration. See also the Interface section. Note that the Telecommuting Module must have at least one IP address which can be reached from the Internet.

•If one of the Telecommuting Module Types DMZ/LAN or Standalone was chosen, move on to the Network Interface 2 page and give the Telecommuting Module at least one IP address on this interface and state the networks connected to the interface. See also the Interface section.

•Go to the Networks and Computers page. Define the networks that will send and receive SIP traffic using the Telecommuting Module. Usually, you need at least one network per interface of the firewall connected to the Telecommuting Module (or, for the Standalone type, per interface of the Telecommuting Module). Some computers should be handled separately, and they therefore need their own networks. See also the Networks and Computers section.

•Go to the Basic Configuration page under Basic Configuration and enter a Default gateway and a DNS server. See also the Basic Configuration section.

•Go to the Access Control page and make settings for the configuration of the Telecommuting Module. See also the Access Control section.

•Go to the Surroundings page (for the DMZ Telecommuting Module Type) and state the networks connected to the firewall . See also the Surroundings section in chapter 4, Network Configuration.

•Go to Basic under SIP Services and turn the SIP module on. See also the Basic section.

•Go to the Interoperability page. Turn Preserve username and SIP URL encryption on.
