Hi All,
I am having a real nagging problem with ssh. I setup dynamic dns so I could I connect to my box from outside.
My basic setup is a router connected to a cable modem. I've opened the firewall port 22 tcp/udp on my router.
However he is the problem I am having.
I can ssh into my box from inside my LAN like, ssh 192.168.0.100, works fine!
However when I try to ssh using my dynamic dns (or the external IP), ssh will hang and never return.
I had a similar problem a few years ago on Bell DSL, the issue was I was SSHing into one of their FreeBSD routers (they fixed this issue a year ago by blocking incoming on port 22), I fixed it by change the SSH port to 2222.
