Syncthing across 2 network

Hello

Computer A in my home network Computer B in my Friend house ( few miles away )

I enabled Port on both side 22000/TCP and Port 21027/UDP

Still not able to connect them i am getting some sort of NAT error or something.

[77B5C] 07:17:17 INFO: quic://0.0.0.0:22000 detected NAT type: Port restricted NAT [77B5C] 07:17:17 INFO: quic://0.0.0.0:22000 resolved external address quic://MY IP :1045 (via stun.syncthing.net:3478) [77B5C] 07:17:43 INFO: Joined relay relay://209.141.:22067 [77B5C] 07:20:15 INFO: quic://0.0.0.0:22000 resolved external address quic://MY IP:1047 (via stun.syncthing.net:3478)

Please advise

Thank you very much in advance

You only need port forward for 22000/TCP. UDP ist only used for local discovery (needs to be allowed by devices firewall; nothing to be done at router level).

You should disable NAT traversal, as this will try to set port forward via uPNP which seems to not work.

Hello I did not disable NAT Traversal yet because my networking bit weak but i did everything else and no luck

Please advise

That’s one half of an error message. If you want people to help you need to provide more information and context.
