AnyViewer can easily connect to remote computers without any special firewall configuration. In most cases, as long as you can access the Internet, AnyViewer can be used normally. When AnyViewer connects to the Internet, it is usually not blocked by a firewall.
However, in some cases, such as in companies with strict security policies, the firewall may block all unknown external network connections. In this case, you need to configure the firewall to allow AnyViewer to connect to the outside through the firewall.
The following are the ports that AnyViewer needs to use:
UDP port: 30196
TCP ports: 30192, 30193
