Normally, the router is responsible for assigning local IP addresses to devices connected to it. Most of the time, it doesn't matter to us what the actual IP address is and whether or not it's always the same. But sometimes it does. For example, some computers connect to network printers using the IP address. So if the IP address changes, the computer can't find the printer. With EchoLink, we have to forward specific ports to the computer running EchoLink using its IP address. So again, it needs to be fixed.
This guide shows how to assign a specific IP address to a specific device using the T3200M that Telus provides.
Make sure that the device you want to change is connected to the network.
Open the router's setting's page to find out the current IP address of the device:
arp -a. This will list all the devices connected to the network.
Back to the router settings page...
If you did this for a printer, you'll now need to tell the computers what the new printer's IP address is.
If you did this for a computer running EchoLink, we now need to forward some ports to it. According to the Echolink website, we need to forward UDP ports 5198-5199. In the router settings page:
