Hi,<br>
<br>
<br>
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.<br>
<br>
But if I'm ssh to server in 012 farm and then from it to the US server is work fine!<br>
<br>
I called 012 technical support but they didn't help me.<br>
<br>
<br>
It's not a FW issue because the ssh session start.<br>
<br>
When I try to ssh it start and after some time fail , here is debug session.<br>
<br>
<br>
ssh -v -l user 111.111.111.111<br>

<br>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.<br>
