 By default, `hbbs` listens on 21114 (TCP, for web console, only available in Pro version), 21115 (TCP), 21116 (TCP/UDP) and 21118 (TCP), `hbbr` listens on 21117 (TCP) and 21119 (TCP). Be sure to open these ports in the firewall. **Please note that 21116 should be enabled both for TCP and UDP.** 21115 is used for the NAT type test, 21116/UDP is used for the ID registration and heartbeat service, 21116/TCP is used for TCP hole punching and connection service, 21117 is used for the Relay services, and 21118 and 21119 are used to support web clients. *If you do not need web client (21118, 21119) support, the corresponding ports can be disabled.*
