Transport mode provides
IPSec service for all applications, thereby simplifying the security operation of the application layer.
An update to
IPSec's IKE protocol is the IKEv2 Mobility and Multi-homing protocol (MOBIKE).
Figure 5 shows the implemented topology using GNS3 to simulate MPLS VPN and
IPsec VPN.
For the
IPSec tunnel establishment between the femto-cell and CGW, the same steps as outlined above are followed.
IPSec is now a requirement, not an option, in the IPv6 specification.
It is possible to use
IPSec to defend against network-based attacks from untrusted computers.
In addition, the
IPSec VPN provided users with a secure connection to our home network, but it did not support user-specific access controls.
The ability to support both SSL and
IPsec VPN tunnels enables the ProSafe Dual WAN Gigabit SSL VPN Firewall to provide both clientless remote access through a secure Web browser interface and legacy support for client-based remote access.
Unlike
IPSec VPN products that require the installation of special client software, the FirePass solution offers a clientless SSL VPN service that leverages any standard browser interface.
