P-2602H(W)(L)-DxA Series User's Guide Table 80 AH and ESP ESP AH ENCRYPTION AUTHENTICATION DES (default) Data Encryption Standard (DES) is a widely used method of data encryption using a private (secret) key. DES applies a 56-bit key to each 64-bit block of data. MD5 (default) MD5 (Message Digest 5) produces a 128-bit digest to authenticate packet data. 3DES Triple DES (3DES) is a variant of DES, which iterates three times with three separate keys (3 x 56 = 168 bits), effectively doubling the strength of DES. SHA1 SHA1 (Secure Hash Algorithm) produces a 160-bit digest to authenticate packet data. AES Advanced Encryption Standard is a newer method of data encryption that also uses a secret key. This implementation of AES applies a 128-bit key to 128-bit blocks of data. AES is faster than 3DES. Select NULL to set up a phase 2 tunnel without encryption. MD5 (default) MD5 (default) MD5 (Message Digest 5) produces a 128-bit MD5 (Message Digest 5) produces a 128-bit digest to authenticate packet data. digest to authenticate packet data. SHA1 SHA1 (Secure Hash Algorithm) produces a 160-bit digest to authenticate packet data. SHA1 SHA1 (Secure Hash Algorithm) produces a 160-bit digest to authenticate packet data. Select MD5 for minimal security and SHA1 for maximum security. 17.3 My IP Address My IP Address is the WAN IP address of the ZyXEL Device. The ZyXEL Device has to rebuild the VPN tunnel if the My IP Address changes after setup. The following applies if this field is configured as 0.0.0.0: • The ZyXEL Device uses the current ZyXEL Device WAN IP address (static or dynamic) to set up the VPN tunnel. • If the WAN connection goes down, the ZyXEL Device uses the dial backup IP address for the VPN tunnel when using dial backup or the LAN IP address when using traffic redirect. See Chapter 7 on page 93 for details on dial backup and traffic redirect. 222 Chapter 17 VPN Screens
