AnyDesk Remote

Ports & Whitelist
AnyDesk clients use the TCP-Ports 80, 443, and 6568 to establish connections. It is however sufficient if just one of these is opened.
AnyDesk’s “Discovery” feature uses a free port in the range of 50001–50003 and the IP as default values for communication.
Local Port Listening
For direct connections, TCP Port 7070 is used for listening by default. This port is opened when installing AnyDesk.

Port Above 1023

TCP and UDP port numbers between 1024 and 49151 are called registered ports. The Internet Assigned Numbers Authority maintains a listing of services using these ports in order to minimize conflicting uses.

Unlike ports with lower numbers, developers of new TCP/UDP services can select a specific number to register with IANA rather than having a number assigned to them. Using registered ports also avoids the additional security restrictions that operating systems place on ports with lower numbers.
