NBG5715 User’s Guid e 121 C HAPTER 18 IPSec VPN 18.1 Overview A virtual private network (VPN) provides secure communications between sites without the expense of leased site-to-site lines. A secure VPN is a co mbination of tunneling, encryption, authentication, access control and auditing.
Chapter 18 IPSec VPN NBG5715 User’s Guide 122 18.3 What Y ou Need T o Know A VPN tunnel is usually established in two phases . Each phase establishes a security association (SA), a contr act indicating what security parameters the NBG5715 and the remote IPSec router will use.
Chapter 18 IPSec VPN NBG5715 User’s Guid e 123 Y ou can usually provide a static IP address or a domain name for the remote IPSec router as well. Sometimes, you might not know the IP address of the remote IPSec router (for example, telecommuters).

Chapter 18 IPSec VPN NBG5715 User’s Guide 138 Figure 85 T wo Phases to Set Up the IPSec SA In phase 1 you must: • Choose a negotiation mode. • Authenticate the connection by entering a pre-shared key . • Choose an encryption algorithm. • Choose an authentication algorithm.
Chapter 18 IPSec VPN NBG5715 User’s Guid e 139 • Aggressive Mode is quicker than Main Mode because it eliminates several steps when the communicating parties are negotiating authenticati on (phase 1). However the trade-off is that faster speed limits its negotiating power and it al so does not provide identity protection.
Chapter 18 IPSec VPN NBG5715 User’s Guide 140 Figure 86 NA T Router Between IPSec R outers Normally you cannot set up an IKE S A with a NA T router between the two IPSec routers because the NA T router changes the header of the IPSec pa cket.
