Dear Expert,
I already set up a Site to Site VPN,
but I found that, when the session is idling, the IKE and IPSEC will cut that session. Because the re-establishment need around 5 seconds to resume the VPN.
The startup time is so long in the first connection.
Can I set something to keep alive the sessions or disallow the auto-drop of the idled session?
Because I don't want to use the ping to keep alive the connection/session.
Any advices?
Thanks!
