Inbound Access with Port Filtering

When you allow inbound access to a machine on a network by public IP, inbound traffic is, by default, allowed on all ports that are open in the CloudShare firewall (see table below). 

The best practice is to allow inbound connections only on the specific ports you require. You can edit the inbound ports (both TCP and UDP) for each net adapter. The ports you add must be in the list of ports open in the CloudShare firewall.

Note

If you need to allow access on a port that is not open in the CloudShare firewall and you cannot modify your software to use a different open port, please contact Support and our IT team will research the feasibility of opening that new port.

To configure inbound access with port filtering:

  1. On the Edit Networks page, select the relevant net adapter, click Advanced Mode and More Details.

  2. Make sure Inbound Access is set to Public IP.

  3. In the Allowed TCP Ports and Allowed UDP Ports fields, enter the ports you want to whitelist, separating the ports with commas.

  4. Click Save Changes.

  5. If the machine's operating system has a firewall, make sure it's also configured to allow the same ports.
