Overview

pfSense contains 3 main VPN technologies, all of which work fairly well.

  • OpenVPN
  • IPSec
  • PPTP

Recommendation

Depending on how your network is setup (and what type of VPN you need), you may want to go with OpenVPN as it not only supports site-to-site and client VPN connections, but is much easier to configure and maintain than IPSec and has much stronger cryptographic technology than PPTP. Many corporations do not allow IPSec and PPTP traffic from within their network to go out to the internet. Since OpenVPN use SSL (TCP or UDP based), you can bypass most of these restrictions. If you are worried about the TCP-over-TCP hate that can sometimes happen when using OpenVPN with TCP transport, you can always use UDP for the transport, which can (sometimes) help with bandwidth utilization and overall quality.
