VPN protocols: what are they and which should I use?

VPN Encryption Up to 128-bit. If your RADIUS server supports multi-factor or two-factor authentication, you can use multi-factor or two-factor authentication with WatchGuard Mobile VPN with SSL. OpenVPN can use a number of symmetric-key ciphers in order to secure data on both control and data channels. The first encapsulation sets up the PPP connection.

Together, these two channels establish and maintain a secure VPN tunnel.

This sounds very impressive until you realize that it only refers to control channel encryption and not the data channel, which is encrypted with mere Blowfish-128 with SHA1 hash authentication. So AES-256 (the AES cipher with a 256-bit key length) is usually considered stronger than AES-128.

For both clients, you must provide the client with a configuration file.

While this isn't encrypted as standard it usually comes bundled with an encryption of 128-bit. Whether this issue also affects SSTP is unclear, but again, hardly inspires confidence. Step 5 Next fill out the “Connection name” and “Server name or address. All “data packages” are sent without the need for approval from the receiving party. OpenVPN runs best on a UDP port, but it can be set to run on any port (see notes later).
