OpenVPN - SSH disconnects every 80 seconds
-
Hi all,
In order to have a site-to-site VPN between our LAN and our AWS VPC, we've installed 2 pfSense this way for using OpenVPN :
All seems to work fine, but problem : when we connect in SSH on a AWS server with BitVise, connection falls every 80 seconds (FlowSocketError). Same result with other SSH clients like Putty.
We tried to reduce the MTU to 1400 with the tun-mtu setting on the OPENVPN client & server configuration, but the problem persists.
We also disabled firewall on both pfSense.
Any help will be very welcome :)
Have a nice day !

Is OpenVPN reconnecting? Do you drop pings or anything else across the VPN?
-
No, OpenVPN stays connected. When i do pings, i have no packets loss. The problem seems to occur only with SSH for the moment…
-
We tried to disable OpenVPN and replace it with IPSEC, we have exactly the same problem.
SSH disconnects every 80sec.
The IPSEC tunnel stays connected.

Are these SSH sessions idle during the 80 seconds?
What happens if you run something that frequently updates like top?
