Using modem-to-modem connection
On the remote computer, install the Dial-Up Networking Server. Use the standard RAS component supplied with Windows. Then configure the server to use TCP/IP. Start the Radmin Server.
On the local computer, install Dial-Up Networking, configure it to use only the TCP/IP protocol and make a call to the remote computer.
Use the remote computer’s IP address to connect to Radmin Server using Radmin Viewer. Typically you will use the IP address 192.168.55.1 for a modem-to-modem connection.
