I'm running RRAS on two servers inside my network, currently able to offer L2TP (via shared key), SSTP and PPTP connections. All three VPN types are working and accessible (as an aside, I'll be ditching PPTP shortly, owing to its lacking security).
I would like to know if there is an easy way to setup on the server side (most ideal) or client side a priority of which connection type to try first, when iniating a VPN connection from client to server. I'd like L2TP to be used as a priority, and if it doesn't work for some reason (like protocol 50 is being block outbound on the remote client side) it switches across to attempting SSTP connection as a secondary choice.
At present, when left on 'automatic' on the Windows VPN client settings, the client just connects up to the PPTP VPN by default (despite having the L2TP shared key in place), utlising the weakest of the VPN technologies we're offering.
