I'm trying to setup shorewall to allow me to ssh in from a remove computer I own. I have added the lines DNAT net loc:192.168.1.2:22 tcp 2097 DNAT loc loc:192.168.1.2:22 tcp 2097 to /etc/shorewall/rules, and re-started shorewall. (I've modified the incoming port in the lines above.) My modem/router accepts incoming calls on this port. Is there anything else I should do? I added the second rule above to test the connection locally, and it works fine. I'm running CentOS-6.5 on both remote and local computers. The reason I'm asking this rather odd question is that the remote computer, in my home in Dublin, is out of action so I can't test the connection directly. My local computer is in Italy, where I am at the moment but am leaving shortly. I'd like to be sure that when I return home I can access the computer here (in Italy). I've tried ssh-ing into the computer here from other remote sites which I do not own, and I am not able to get through. The connection is not forbidden, but I do not login to my local computer; the connection simply hangs: tim@lanczos:~> ssh -v -p2037 anghiari.homelinux.com OpenSSH_6.1p1, OpenSSL 0.9.8y 5 Feb 2013 debug1: Reading configuration data /u2/staff/tim/.ssh/config debug1: /u2/staff/tim/.ssh/config line 37: Applying options for * debug1: Reading configuration data /etc/ssh/ssh_config debug1: Connecting to anghiari.homelinux.com [79.43.123.229] port 2037. (Nb Port changed.) This could be due to some rule at the remote site; or it could be that I need to do something extra at this site? I checked with wireshark, and ssh packets are arriving at 192.168.1.2, as requested. Any advice or elucidation gratefully received. -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland ------------------------------------------------------------------------------ CenturyLink Cloud: The Leader in Enterprise Cloud Services.
