• 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.

– See "Setting Up a Client-to-Gateway VPN Configuration" on page
– See "Setting Up a Gateway-to-Gateway VPN Configuration" on page
