How to remote control using Expert Assist to a machine behind a firewall (SL438)

In order to access a computer that is behind a router one of the router's ports needs to be mapped to the IP address and port of the machine on which the Expert Assist remote control service is running.

From outside the LAN, you would gain access to the computer running the Expert Assist remote control service by entering the router's IP address and the port to which the desired machine is mapped.

For example:

ROUTER: External IP address: 111.111.111.111
The Desktop Authority remote control service machine: IP address: 192.168.0.10, Port: 2000 (Port 2000 is the default but this can be changed.)

STEP 1:

Map a port from the router to the computer. In this case, a port on the router is selected (for example, 5200), and then map it to 192.168.0.10:2000.

Mapping ports from routers to computers is router specific. Typically a router will have a web-based interface that allows it to be configured and to maintain it. Sometimes router companies refer to this action as 'Port Forwarding' or 'Port Mapping'.

STEP 2:

After mapping the port, you will now be able to fully access the Expert Assist remote control client computer with the URL http://111.111.111.111:5200 or https://111.111.111.111:5200 - that is the router's external IP and the port that was mapped to the client machine.
