The tunnel was created with:

ssh -f -n -N -R 2205:127.0.0.1:2206 lvl at 192.168.253.52

Actually, I just tested on another machine - same problem:

# ssh localhost -p 2205
The authenticity of host '[localhost]:2205 ([::1]:2205)' can't be
established.
ECDSA key fingerprint is 99:ff:ea:83:b4:5f:bf:79:13:6f:75:83:0e:16:fe:d2.
Are you sure you want to continue connecting (yes/no)? ^C

# ssh 192.168.253.52 -p 2205
ssh: connect to host 192.168.253.52 port 2205: Connection refused

It looks like the tunnel binds only to localhost, which could be the
problem:

tcp        0      0 127.0.0.1:2205          0.0.0.0:*               LISTEN
tcp        0      0 ::1:2205                :::*                    LISTEN

How would one bind it to *all* ports? This test machine is SuSE, and I
have opened 2205 in the firewall.
