Describes what information is new or significantly changed in this release.
New Function: Traffic Flow Confidentiality (TFC)
Traffic Flow Confidentiality (TFC) allows you to conceal the actual length of the data packets transferred over the VPN connection. Use TFC for extra security against attackers who might guess the type of data being sent over the VPN connection from the length of the data packet. You can only use TFC if your data policy is setup for Tunnel Mode.
New Function: Extended Sequence Number (ESN)
Extended Sequence Number (ESN) allows your VPN connection to transmit large volumes of data at a high speed with out having to frequently re-key. You can only enable ESN when your data policy uses the Authentication Header (AH) protocol or the Encapsulation Security Payload (ESP) protocol and AES as the encryption algorithm.
New Scenario: Firewall Friendly VPN
In this scenario you can learn how to establish a VPN connection where the gateway (client) and the host (server) are behind a firewall running Network Address Translation (NAT).
