It connects to XXX.XXX.XXX.XXX port YYY, using a source port of "srcport" and binds the tunnel on local port "locport". Then you can connect to localhost:locport.

* It requires socat
- port 8080 on localhost will be a SOCKSv5 proxy
- at localhost:localport1 you will be connected to the external source server1:remoteport1 and at bind_address2:localport2 to server2:remoteport2
- you will be using only IPv4 and arcfour/blowfish-cbc, in order to speed up the tunnel
- if you lose the connection, autossh will resume it at soon as possible
- the tunnel is here a background process, wiithout any terminal window open
