Comment on Weird Wireguard issues I could use some help with.
taaz@biglemmowski.win 11 months agoYeah I would probably try if the phone can actually access anything on that port.
On router: netcat -vvvl 0.0.0.0 51820
On phone: http://router_ip:51820
The browser will fail opening it but on router you should see the first incoming HTTP GET packet.
Or one could run a local shell on the phone (assuming android) and try netcat too.

I have an network tools app that lets me test arbitrary ports and I do see those packets on a tcpdump, but this app (and you’re suggestions above) are all TCP while Wireguard listens on UDP. I haven’t come up with a way to test UDP from the phone yet.

Netcat can do UDP with
-uflag, to get netcat on the phone (android) you could try local shell (Connect Bot app can do it) and try calling the local netcat (nc, though it’s a simple busybox implementation so it might not have all the features). Though not sure if udp would just work like that.nightrunner@lemmy.world 11 months ago
They call it a tcpdump but Wireshark analyzes all network traffic. You can use the udp.port == 51820
Do you have a laptop? Probably more tools and easier to test from there.
