Ahh I see... Thank you. The process with PID 7460 using the open port 5081 actually is... ...Sync! OK I'll leave it there. BTW, it syncs now via WiFi. For some reason, it seems that the MAC address that I set it to had not been saved in the settings. I'll report if it continues to work after a reboot.

OK thank you. There, I get: C:\Windows\system32>netstat -ano | findstr 5081 TCP 0.0.0.0:5081 0.0.0.0:0 ABHÖREN [LISTEN] 7460 UDP 0.0.0.0:5081 *:* 7460 So it seems that port 5081 is not used, right? Yes, Listening port. Should I leave that at port 5081 (this is one of the only four ports 25, 443, 5080, 5081 that are open here at the office LAN).

Thank you very much, will do so and report back. However, I can't use "lsof -i :5081", because this seems to be Unix/Linux, and I am on Windows. What port would be the default Sync "Connection Port" in the advanced preferences?

Thank you for the information. I have set the respective preference to the Mac address of my Wi-Fi adapter using the syntax 00:80:41:ae:fd:7e However, Sync still only connects if I unplug the LAN cable first and then start Sync. If afterwards Sync is connected, I can re-plug the LAN cable, and Sync stays connected over WiFi. So is there something else that can be done in order to make sync directly connect using the Wi-Fi adapter, without having to unplug the LAN cable first? Additionally, I changed "Connection Port" in the advanced preferences to "5081" (because this is one of the four ports 25, 443, 5080 and 5081 that are open in the Office LAN here). Should I change this setting back, and if yes, to which port?

Hi forum, when I installed Sync a few months ago in the office and at home, it would connect instantly and syncing would work perfect. However, in the meantime Sync has stopped working for unknown reasons. The only ports that were open and still are in the Office are the following: 25 443 5080 5081. Sync does not connect anymore and does not show Peers as online. In the office there is also a Wi-Fi network. If I unplug the LAN cable, and thus I am online over Wi-Fi instead of over LAN-cable, then Sync instantly connects and shows all Peers as online. Therefore the question is, is there a way to bind Sync such that it only connects over the Wi-Fi network adapter? This used to be possible using ForceBindIP, but it seems that ForceBindIP does not work anymore on Windows 10. Is there a setting in Sync that makes Sync connect only over a manually specified network adapter? Thanks for help David
