Virtual Network Gateway - Route Based Idle timeout

Hi,

I am looking to setup a route based Virtual Network gateway that only needs to be up during business hours (8am tp 6pm Mon-Fri). Is there a way to configure the idle timeout on a VPN to allow this?
Also when i turn off keep-alive on the Sonicwall NSA 4600 it drops the connection, so it seems this is required. Having looked at the policies available, they seem to relate specifically to the IKE encryption rather then an idle timeout.

Any suggestions would be greatly appreciated.

thank you,
Richard

@RichardCarrick-9297 Thank you for reaching out to Microsoft Q&A. I understand that you are trying to setup a timeout value for your VPN so that when there is no traffic traversing the VPN, it should go down.

This is possible with a Policy Based VPN as seen from the VPN FAQ here.

However, when you have a Route Based VPN, this is not the behavior. There is no option as such to acheive this setup from Azure side. I would suggest you to reach out to Sonicwall Support to check of they have any features for the same.

Regarding Keep Alive, this is needed when any of the sides are behind a NAT device so you may not be able to keep the tunnel up if this is disabled. Hope this helps.

Please let us know if you have any further questions and we will be glad to assist you further. Thank you!
