The best method is to forward the port 23 (TCP only) to a non-existent IP, such as 10.0.0.200. If a user tries to telnet into your router from the internet, the request will be handled by this port forward setting, which will forward the request to the non-existent IP that you have used, so they won’t be able to connect to the router directly. When you have setup the virtual server, save & reboot, including a power off from the plug for 30 seconds. If you wish to test it, use another internet account (the PAYG will be fine) and select Start | Run | type cmd (or command) | telnet and press . You shouldn’t be able to connect – if you can, then anyone on the internet can do the same (assuming they know your password). Do not try and use the same internet account that supplies your broadband because you will be on the same network as the router and will always be able to telnet in.
