Hi guys,


Just a quick question. We have one VPN gateway used by 2 phases 2 on a USG40W as we have on many other router without any problem.

On this one, for an unknown reason, phase 2 are never connected both at the same time, there are dropping all the time, sometime we can ping through these phase 2 but it is very unstable.

I tried with firewall off and it's still the same.

In the debbug logs, I notice some weird error regarding IPSec, why would IPSec drop packet ?


Thanks for help,


Davy
