I have a strange problem logging into my machine via ssh. Some time ago it worked perfectly, but now it doesn't.
I'm connected to thze Internet with a router, so I use NAT.
When I login via ssh using my local IP 192.168.2.100, it works. But when I try to login using the public IP 184.108.40.206 or so, I get the following error:
me@mymachine:~/.ssh$ ssh -p 1007 220.127.116.11 -vvvv
OpenSSH_4.2p1 Debian-7ubuntu3.1, OpenSSL 0.9.8a 11 Oct 2005

(I use 1007 as my public port; the problem persists if i switch to port 22)
I appreciate any advice,
