I'm trying to access two different machine's VNC servers located on the same local network from the WAN.
As I'd like that traffic to be routed in an SSH tunnel, I'm using
ssh email@example.com -N -L 15900:127.0.0.1:5900 and then
vnc://firstname.lastname@example.org:15900, with no problems for the first machine.
For the second machine I NAT'ed the port 2222 to the port 22 of this machine's IP in my router. The NAT is also configured to forward port 5900 to the first machine's IP and the port 5901 to the port 5900 of the second machine's IP.
I assumed that
ssh -p2222 email@example.com -N -L 15901:127.0.0.1:5901 and then
vnc://firstname.lastname@example.org:15901 would work, but it doesn't.
The shell where I'm running the
ssh -p2222 email@example.com -N -L 15901:127.0.0.1:5901 command outputs:
channel 2: open failed: connect failed: Connection refused
when I try to VNC into the machine.
ssh -v -p2222 firstname.lastname@example.org -N -L 15901:127.0.0.1:5901
and I got:

Has anybody any idea?
