WebIPSec. GETVPN uses ESP (Encapsulating Security Payload), the same as traditional IPSec VPNs.It only supports tunnel mode which encapsulates the entire IP packet which adds a new IP header. There is a twist however, GETVPN uses tunnel mode with address preservation.This means it copies the inner IP header to the outer IP header, without any … WebIPsec (Internet Protocol Security) is a security protocol that uses an optional Internet Protocol function to prevent data manipulation and ensure the confidentiality of data …

With tunnel mode, the entire original IP packet is protected by IPSec. This means IPSec wraps the original packet, encrypts it, adds a new IP header and sends it to the other side of the VPN tunnel (IPSec peer). Tunnel mode is most commonly used between gateways (Cisco routers or ASA firewalls), or at …
