We share useful information for users of virtual machines. Our clients often contact Tucha technical support service with a question about how to configure port forwarding to the server located in a private network, and each time we send a detailed and clear instruction in response.

7. Select the range of ports on the server to which traffic should be forwarded (Private Port), select the range of ports on the virtual router (Public Port), and the protocol (Protocol). Next, click the Add button:


8. Last step is to select the server to which this traffic should be forwarded and its address:
