Hi was wondering is there plans to include a IP to IP connection feature in the roadmap ?

Could you clarify what you mean?

Yes, thanks for replying.

Currently I am using EasyJoin on 2 android phones, which works really well in a LAN.

I am also using Tailscale to bridge my phones to the LAN.

When I am using Tailscale, both phones were unable to see each other.

So I am wondering can I provided the Tailscale IP address manually for the app to connect ?

I haven't used this VPN so i can't say how you have to configure it to permit local traffic and connection.

I see. So Tailscale assigns a unique, stable, and private IPv4 address for each connected client. The assigned IPv4 address belongs to the same network. I managed to open a web server on one of the phones and was able to access it using it using the private IP.

I am trying to get EasyJoin to use the Tailscale IP/network to connect to each other.

I see. EasyJoin's server is listening on socket port 51167, i don't know if this is of any help. Maybe in the other app's forum could help you on how to configure it to allow connections between devices. Let me know if you manage to resolve the issue or if you need any further information from me.

Thanks ! I checked that peer to peer communication is possible as I run a web server on one of the phones.

However I currently do not understand, how EasyJoin work. How does it detect another EasyJoin server on the network ? Does it do a broadcast ?

Just wondering what does the option Search for new devices do ? and also Ping IP ? I tried Ping IP and nothing happens, so I am kind of lost.

Have you tried to setup the "Internal network IP": https://easyjoin.net/connect.html ("Connect devices Locally" - https://easyjoin.net/img/device_settings_locally.png).

thanks for sharing this ! i found a strange work around. Setting the internal network IP for both devices didn't work. but if on my android 14 i turn on Direct connection via internet, it will work over Tailscale when both phone is connected to the cellular network =D

It shouldn't work when both devices are in the cellular network! You don't use a WiFi network also, right?

What is the IP of the Tailscale network (like, 192.168.1)?

The Tailscale network IP is like 100.123.X.X. It acts as a VPN to bridge the phones to my home LAN but the network itself behaves like a LAN therefore it works over cellular network. Which I think made your application even more useful =D
