Hi,
So in my “POC” with syncthing, I have noticed that I haven’t opened the port discovery broadcast.
Quote from the syncthing doc for " Port 21027/UDP: for discovery broadcasts on IPv4 and multicasts on IPv6
The system seems functional even with that port close
What is that port exactly used for ?
Here my setup:
- discovery server – inbound open: 8443 (TCP)
- syncthing server – inbound open: 22000 (UDP/TCP)
- syncthing client – inbound open: 22000 (UDP/TCP)
- Port forwarding on syncthing servers and syncthing client for the port 22000
So basically what’s the use of the port 21027 and where in my setup i should open that ?
Followup question: is there any way to customize that port?
