AX1800 - Reverse ssh fails

[GLrs]

@donvito7

ssh -p xxx -fN -R 4343:localhost:22 my_user@PublicIP_of_My_Laptop

binds port 4343 on your laptop to SSH (your command requests to forward everything arriving at port 4343 of the laptop to port 22 on the AX)

@donvito7

ssh -g -L 4343:192.168.8.200:22 -p xxx my_user@localhost_of_My_Laptop

tries to bind port 4343 on your laptop to SSH - which it cannot bc it’s already bound to SSH by your other command (your command requests to forward everything arriving at port 4343 of the laptop to port 22 on 192.168.8.200).

As written in my last reply: You only need the latter command

@GLrs

On your laptop you do ssh -fN -L 4343:192.168.8.200:1234 my_user@asd123f.glddns.com (or use PuTTY or another SSH client)
You then opened localhost:4343 in your web browser (or connected your app to localhost:4343).
