Users are reporting me that the mobile VPN disconnect after 8 hours of activity. 

It's an IPSEC VPN, I've searched for a timeout parameter that could cause this disconnection in the following areas: 
- into the gateway settings (phase1)
- into VPN Connection settings (phase2) 
- into object > users

Into object > users i've found the Lease Time and the Authentication time parameters which seems interesting, but the default value is 1440 minutes corresponding to 24h so does not match the 8 hr connection timeout people are reporting me. 

The clients use the native VPN Client of windows10 accessible from "Start > VPN Settings" or in the taskbar. It could be also the client to close connection but i've found no usefull  information online. 

Any Idea about this?
Thank you

    Hi @phphil

    Check the SA Lifetime parameter at VPN Connection and VPN Gateway profiles. Maybe the value is 28800 sec which is 8h

    In my case it is set to 24h (86400) on both phase 1 and 2

    Must be something else, thank you anyway : )

    Hi @phphil,


    Could you please share your IKE and IPSec logs with me by private message?

     

    Best regards.

    Solved:

    according to this [SOLVED] Watchguard SSL and L2TP/IPSEC VPN always drop at set time - Spiceworks

    Windows native VPN client has a timeout every 7.6hr which trigger a rekey, this rekey fails.
    On the firewall, decreasing the SA Life of Phase 1 (Gateway settings) to a value < than 7.6hr will solve the issue since the rekey will be triggered before that the one triggered by Windows.
