I am just implementing a VPN for some 20-30 users to work from home. I decided for SSTP as it is standard in Windows and very secure. L2TP/IPsec with PSK is also great, but can have some issues and is often blocked by mobile providers, etc.
I am wondering is there a practical speed difference between the two? We have a 50 MBit/s sync link and RB3011.
