Model D1-713P Router

D-Link offers several router units with different models of routers with integrated multi-port swicthes.  This an example of their current offering for both wired and wireless networks.  Although the eyesite 140 does not have an 802.11B interface, D-Link wireless routers also provide RJ-45 connections for use with wired systems.

Step 1:  Install the Router Between Your Cable/DSL Modem and Your LAN.

Follow the recommended procedures for setting up your D-Link router.  In most cases, you will simply need to unpack the unit, connect a CAT-5 cable from your Cable Modem or DSL modem and the WAN port of the router, and connect your PC(s) or other computing devices to the LAN ports.  Next, connect your eyesite 140 to one of the available LAN ports on the rear of the unit.  Everything on the LAN side should work as it did before the router was installed, and your PC should be able to surf the internet without any special setup of the router unit.

Step 2:  Check the Public Internet or WAN Address for Your Site.

Use your web browser to check the configuration of the router.  This is done by entering the address of the router into the URL field of your browser.  Typically, the default address of the router is  Once you have entered the password to gain access to the router, you can click on the status tab to see what the current WAN address is for your site.  The address shown will be the address to use when dialing into the system behind the firewall.


Step 3:  Create a UDP Port Map to Your Local eyesite System or PC.

Establishing a connection through the firewall by dialing out through the firewall will not be a problem.  The firewall is designed to protect your local machinery from unauthorized access from the WAN side of the firewall, so unless the router is configured further, outside systems will not be able to establish a connection to anything behind the firewall.  The firewall has the ability to map PORT numbers to local LAN addresses for specified types of IP traffic.  To create a PORT mapping for your eyesite 140 click on the ADVANCED tab and create a entry similar to the following example.  Next, click APPLY at the bottom of the screen to enable the mapping to the local system.  You can use any PORT range you like but we recommend using 9000-1000 or 50000-60000 to avoid any possible conflicts with widely used ports from other network applications.dvance

Step 4:  You Are Now Ready to Go!

Now that you have created a PORT map for your local system it is possible for systems outside the firewall (either another eyesite 140 or eyesite for Windows) to call into the local system.  The address they should use is the WAN address as discovered in Step 2, followed by the PORT number as configured in Step 3.  In this example, the eyesite system could be dialed by entering the address in the calling system.
