My home PC is behind NAT but my router has static ip address. My work PC uses 3G stick for Internet (So I guess it is like being behind NAT).I would like to create a reverse SSH-tunnel to connect to my work PC. Following lots of manuals I create a tunnel on my work PC:ssh -R 33333:localhost:22 homeuser@135.142.205.131Where 135.142.205.131 is my router's static IP address.When trying to connect to work from home I isssue:ssh -p 33333 localhostBut I get connection refused. I think I need to configure some port forwarding because I think I need to somehow make ssh let me connect some local port to my router's 33333 port to make the tunnel work.How do I do it?Output at my work PC:netstat -nap --inet --tcpProto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program nametcp        0      0 0.0.0.0:56789           0.0.0.0:*               LISTEN      1402/klienttcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      -tcp        0      0 10.0.85.14:56731        104.20.90.217:443       ESTABLISHED 1402/klienttcp        0      1 10.0.85.14:52501        135.142.205.131:22      SYN_SENT    2366/sshtcp        0      0 10.0.85.14:56789        52.49.10.125:53633      ESTABLISHED 1402/klienttcp        0      0 10.0.85.14:47118        104.20.89.217:443       ESTABLISHED 1402/klientOutput of netstat - output at my works PC:Active Internet connections (w/o servers)Proto Recv-Q Send-Q Local Address           Foreign Address         Statetcp        0      0 10.0.85.14:56731        104.20.90.217:https     ESTABLISHEDtcp        0      1 10.0.85.14:52501        135.142.205.131:ssh     SYN_SENTtcp        0      0 10.0.85.14:56789        ec2-52-49-10-125.:53633 ESTABLISHEDtcp        0      0 10.0.85.14:47118        104.20.89.217:https     ESTABLISHED
Setting up port forwarding on router for reverse SSH tunnel
linux;ssh;ssh tunneling;port forwarding
This line: tcp 0 1 10.0.85.14:52501 135.142.205.131:22 SYN_SENT 2366/sshtells us, that the ssh-connection from the work pc to the home-pc has not been completed. So eithera) the port forwarding from the router to the home-pc does not work, orb) the ssh-d on the home pc is not listening to the (correct) address
