Microsoft MVP Richard Hicks walks us through Load Balancing SSTP VPN and the advantages it brings to network security:
1. SSTP uses TLS
2. Operates on Standard HTTPS port 443
3. Commonly Available
4. Easy to Implement and support
1. Easy to load balance
2. Native support for TLS (SSL) termination/offload
3. All encryption/decryption can be performed on a dedicated appliance.
L2TP/IPSEC and PPTP are legacy VPN protocols and are obsolete - they should be avoided at all costs.
