Which ports does AnyDesk use?To connect to the AnyDesk network port 80, 443 or 6568 is used. For standard listening port direct line connection is 7070 (TCP).
補充: 我實測是7070有效.

TeamViewer Ports
TCP/UDP PORT 5938
TeamViewer prefers to make outbound TCP and UDP connections over port 5938 – this is the primary port it uses, and TeamViewer performs best using this port. Your firewall should allow this at a minimum.
TCP PORT 443
If TeamViewer can’t connect over port 5938, it will next try to connect over TCP port 443.
However, our mobile apps running on Android, iOS, Windows Mobile, and BlackBerry don’t use port 443.
Note: port 443 is also used by our custom modules which are created in the Management Console. If you’re deploying a custom module, eg. through Group Policy, then you need to ensure that port 443 is open on the computers to which you’re deploying. Port 443 is also used for a few other things, including TeamViewer update checks.
TCP PORT 80
If TeamViewer can’t connect over port 5938 or 443, then it will try on TCP port 80. The connection speed over this port is slower and less reliable than ports 5938 or 443, due to the additional overhead it uses, and there is no automatic reconnection if the connection is temporarily lost. For this reason, port 80 is only used as a last resort.
Our mobile apps running on Android, Windows Mobile, and BlackBerry don’t use port 80. However, our iOS apps can use port 80 if necessary.
