Log: New external port opened

Hello all,

I use a portable to be synchronized by a server, now I am in LAN with the server, what does this log row means ?

[J5MDR] 2024/12/10 21:18:59 INFO: New external port opened: external TCP address(es) [external_server_ip:18928] to local address [::]:22000.

Syncthing can use UPnP to attempt to allow inbound connections on your Internet gateway. See Firewall Setup — Syncthing documentation for more information.

If you don’t want Syncthing to do this, in the GUI go to Actions/Settings/Connections and turn off Enable NAT Traversal.
