Parameters recommended by the VPNC and used in the VPN Wizard Parameter Authentication Protocol Diffie-Hellman (DH) Group Key Life IKE Life Time NETBIOS Factory Default SHA-1 Group 2 (1024 bit) 8 hours 24 hours Enabled • What level of IPSec VPN encryption will you use? - DE - The Data Encryption Standard (DES) processes input data that is 64 bits wide, encrypting these values using a 56 bit key. Faster but less secure than 3DES. - 3DES - (Triple DES) achieves a higher level of security by encrypting the data three times using DES with three different, unrelated keys. - AES • What level of authentication will you use? - MDS - 128 bits, faster but less secure. - SHA-1 - 160 bits, slower but more secure. Note: NETGEAR publishes additional interoperability scenarios with various gateway and client software products. VPN Tunnel Configuration There are two tunnel configurations and three ways to configure them: • Use the VPN Wizard to configure a VPN tunnel (recommended for most situations): - See "Setting Up a Client-to-Gateway VPN Configuration" on page 5-5. - See "Setting Up a Gateway-to-Gateway VPN Configuration" on page 5-19. • See Chapter 6, "Advanced Virtual Private Networking" when the VPN Wizard and its VPNC defaults (see Table 5-1 on page 5-4) are not appropriate for your special circumstances. 5-4 Basic Virtual Private Networking v1.0, September 2007
