SQL Server and VPN

I have Point to poin开发者_开发技巧t VPN Configured, and i am making use of SQL Server, i am able to connect the database while after few minutes it issues an error that connection has been closed.

I suspect you may have issues with MTU or inspection if Cisco. Probably not the best place to ask so try serverfault.com

Can this help you ?
how long must a sql server connection be idle before it is closed by the connection pool?

No problem here. If this is related to teh VPN (as opposed to things like general network problems) it must be very specific to your VPN setup, or some internal system.

I use Windwos VPN technology (client or office / office with RRAS) and as I said - no problems.
