Hi,
I have a route based VPN between a SSG520 and a supplier. Every 90 seconds the VPN goes down and then comes back up again.
I have VPN Monitor, Optimised and Rekey all enabled for this VPN. If I turn these off then the VPN doesnt establish at all. - I suspect this is because the tunnel interface is down so rather than routing via the tunnel it simply sends the traffic out the default route.
Has anyone else had this problem? and are there any tricks I can do to either have the VPN only come up when needed, or have it stay up for longer than 90 seconds each time?
The SSG520 is running 6.0.0r6.0. A route based VPN has been used because I have to use a MIP to hide a machine on our side behind a public IP, which I couldnt get going under a policy based VPN.
