Make FCT more resilient to network disruptions?

[Magion]

With many employees working at home now, I regularly receive e-mails of employees complaining about VPN connection drops. All of them are using wifi at home, so occasional drops are to be expected. However I would expect FCT to be able to handle short network outages, but it seems like even very short interuptions result in a dropped VPN connection.

We are using SSLVPN on a FGT 6.0.11 and FCT 6.0.9

Is there some way to make FCT more forgiving, and wait a bit longer to see if the connection will be restored before dropping the connection?
