Hi there brief question about firewall config (and documentation of syncthing on its doc site) regarding kcp: do we need to forward/open another additonal udp port 22020 as during a fresh startup/restart of 0.14.40 i see these kind of log lines:
[XXXA] 20:04:52 INFO: kcp://0.0.0.0:22020 detected NAT type: Port restricted NAT [XXXA] 20:04:52 INFO: kcp://0.0.0.0:22020 resolved external address kcp://126.96.36.199:22020 (via stun.counterpath.com:3478)
I have forwarded for a long time on the nat gateway device some 22000 port or things like that according to what I found back then in the syncthing doc pages https://docs.syncthing.net/users/firewall.html
can anyone update those or be more precise in these technical details? thank for your software and the efforts. cheers.
p.s. My router even supports and does feature upnp, so I wonder if I need manual forward at all to begin with, but I added the 22000 back then manually. But the kcp a.k.a. udp port didnt become handled via upnp mechanism by the syncthing code. is this a bug?
