Publisher: Addison-Wesley Professional

Tunnel mode is often used to provide connectivity between networks that use private addressing; the outer IP packet's address is routable and allows delivery of the inner IP packet from one private site to another. My split tunneling articles illustrate servers with private addresses) then you must ensure public IPsec traffic is forwarded to the VPN server. VPNs Illustrated: Tunnels, VPNs, and IPsec by Jon C. Traditional ATM and Frame Relay circuits are referred to as Layer 2 VPNs, whereas IPsec tunnels over the Internet are called Layer 3 VPNs.

If you use a Linux based router gateway, and MAC-OSX Mountain Lion, being able to created an IPSEC VPN tunnel back to your home site can be very useful. This involves three components: Windows Server When finished, you should have one policy that specifies MS-CHAP v2 authentication for L2TP tunnels, and one policy that specifies PEAP authentication for PPTP tunnels. The MAC-OSX Lion IPSEC We will start with a fully commented racoon.conf example based on the above information in order to illustrate how to configure an IPSEC VPN.

When the VPN connection is established between 2 parties (between a VPN client and VPN gateway or between 2 VPN gateways), a secured virtual tunnel will be created with capability to encrypt the data (so no hacker can see the data content ), preserve data integrity (no data change during transmission) and ensure the communication only happen between that 2 authenticated parties. The remote access VPN is supported by L2F, PPTP, L2TP and IPsec tunneling protocols.
