Replications freeze because of sshd timeout

[jp34]

Hi,

« ClientAliveInterval » section in « /etc/ssh/sshd_config » file is set to 300 sec and replications send data (bandwith increases) then freezes 300sec after (bandwith falls to 0).
Why does sshd close connection whereas veeam is replicating ?
ESX servers communicate via IPSec VPN, can "ping fragmentation" explain this issue ?
What's the max value of « ClientAliveInterval » section ? what about illimited value ?

Thanks.

Let's take a look at this post about fragmentation over VPN:
