Thanks for all the
replays,
Now after 3 day it
suddenly stat to work. I didn't done any change in both sides.
My guess is that 012
block port 22 abroad, because of some ssh worm that attract from local
PC's and consume bandwidths etc.

Hi,
I have weird problem , staring this morning I can't ssh to a server in
US, from some computers that connect to the Internet using 012 cabels.
But if I'm ssh to server in 012 farm and then from it to the US server
is work fine!
I called 012 technical support but they didn't help me.
It's not a FW issue because the ssh session start.
When I try to ssh it start and after some time fail , here is debug
session.
ssh -v -l user 111.111.111.111
Try to see if /sbin/ifconfig eth0 mtu 1200 helps
(or whatever your Ethernet NIC might be)
When Israeli ISPs play with QoS boxes, they have this weird side effect
of lowering the MTU...
And I have been experiencing MTU issues lately in 012 (as a business
user on a fiber connection). For me, going down to 1400 sufficed in
solving all the weird connectivity issues I had. I am asking you to try
lower because if you're on cables, there are MORE tunnels involved...
if it solves the problem, you can go up on a trial-and-error game.
HTH,
