As of recently, on my Windows PC, Syncthing creates seemingly endless firewall prompts, even if I tell the firewall to allow Syncthing to do anything it likes. Might the problem have to do with lack of port-forwarding, or with ‘upnp’? I found this page of instructions, but the instructions are unclear. For one thing: the instructions leave it unclear whether I need any kind of port-forwarding at all. Do I? If I do, just how do I set it up? Thanks.
(I found two other questions along similar lines on the forum. However, I do not understand the answers to those questions.)
