Forcing site to site altime UP



I'm trying to site to site VPN to be up all the time even when there is no traffic

I went through this KB but didn't help

What happens here is that our S2S goes down from time to time , if there is no traffic or after specific amount of time , and goes UP under two conditions:

1- If I manually bring it up.

2- If there is a traffic.


How can make it all the time up?


I'm running FGT1000D v.5.6.11

The other side is Checkpoint - not managing it and absolutely will not


And here is my p1+p2 conf:

i dont see the keepalive enable in the phase2 you show


Because of "set auto-negotiate enable".

If this setting is enabled then keepalive disappears from phase2 settings.

But i tried that also.


Valued Contributor

ah, what do you see when you do a debug vpn? do you see the phase 2 being attempted or not at all?


if not then i would open a support case because that should happen.
