I wish to give my software development team, access to a server on my LAN over ssh (secure shell) connections coming in from the Internet.I have setup an "Incoming Filter" in my ADSL router to forward *all* incoming connections on port 30303 to the LAN server on 192.168.90.2 port 22.Yet when my developers try to connect using "ssh -p 30303 @," they get an immediate "Connection refused."This is unexpected behaviour since I have set the port forwarding rule in the ADSL router. I have been able to do this in the past (about two-three years ago).FWIW, there are no firewall rules on the LAN server.I suspect that either my ADSL modem is flaky or MTNL is blocking such connections with some kind of L7 filters.Has anyone else experienced blocking of incoming connections to ssh?
