I am facing some issues when connecting to SSH and others services like gitlab. It just happens when connecting by Wi-Fi at home, as I am able to work with it when I am connected to any different one or using my mobile data, so it should be because my router. This internet service is a new contract with my provider so never could use it before.
I have called my ISP, they told me I am already out from the CG-Nat and I am able to open ports (as I though it was because this reason) and have the 22 added in my opened port list but it still not connecting when using SSH.
My router model is a Sercomm FG824CD and I opened the 22 port with these parameters: Device: Mydevicename IP LAN: 192.168.1.** (my device IP Protocolo: TCP Public port: 22 Puerto LAN: 22
The only thing I don't understand, is that if I try to add my mobile phone's IP in order to use SSH as well from this phone, the router tell me ¨port 22 is still used, choose another port¨. But I don't get the point... what if I want to open this port for my phone? Can't I?
Sorry for my ignorance and thank you. I hope you can help me
[EDITED]
I have realise that my MacBook can connect SSH through Wi-Fi (can't with my Linux laptop), so maybe it’s not the router… I tried to connect SSH with my Manjaro Laptop and by my mobile phone which has a custom android version ( /e/project ) having no results.
Return of SSH when trying to connect by Wi-Fi:
