If you've followed the steps presented above, your configuration should be finished. But as with any other configuration, it is always wise to test the setup in order to make sure that it works properly. In order to test a PPTP connection, | If you've followed the steps presented above, your configuration should be finished. But as with any other configuration, it is always wise to test the setup in order to make sure that it works properly. In order to test a PPTP connection, log in to one of the routers' WebUIs and go to '''Services → CLI'''. Log in with the user name: '''root''' and the router's admin password. You should then be able to '''ping''' the opposite instance, i.e., if you logged in to the server's CLI, you should be able to ping the client's virtual IP address, and vice versa. To use a ping command, type '''ping <ip_address>''' and press the "Enter" key on your keyboard: | ||

If you're using the server as a default gateway, end devices connected to the PPTP client router should have the Public IP address of the PPTP server.
