Protocol
The IPsec protocol defines the method of encryption and authentication to use through
the IPsec tunnel. You can choose between two modes: DES-MD5-96 or 3DES-MD5-
96. Encoding is provided by DES (Data Encryption Standard), a secret key cryptog-
raphy method. DES uses a 56-bit key, while 3DES (tripleDES) uses a 168-bit key.
Authentication is provided by MD5 (Message Digest 5). The message digest allows
the receiver of a packet to ensure that a packet has not been altered en route from the
sender. MD5 is described in RFC1321.
Choose IPsec Tunnel #1 or IPsec Tunnel #2 from the Security Settings sub-
menu.
