In transport mode, the outer header, the next header, and any ports that the next header supports, can be used to determine IPsec policy. In effect, IPsec can enforce different transport mode policies between two IP addresses to the granularity of a single port. For example, if the next h...
The IPsec standards define two distinct modes of IPsec operation, transport mode and tunnel mode. The modes do not affect the encoding of packets. The packets are protected by AH, ESP, or both in each mode. The modes differ in policy application when the inner packet is an IP packet, as...

IPSec VPN tunnel mode Good day, I have the following question, hoping you can help me. In IPSec VPN, which of the following scenarios can be applaied by tunnel mode a) between the host and the host b) between hosts and security gateways c) between security gateways d) between tunnel mo...
Figure 6.8 shows IPSec in tunnel mode encrypting traffic end-to-end between two computers: a line of business (LOB) application server running Windows Server 2003 in a perimeter network, and a computer running SQL Server that functions as a data store for the application server in an internal...
protecting traffic between different networks, when traffic must pass through an intermediate, untrusted network. Tunnel mode is primarily used for interoperability with gateways, or end-systems that do not support L2TP/IPSec or PPTP connections. You can use tunnel mode in the following configurations...

IPsec has two modes of operation: IPSec Tunnel mode: The entire original IP packet is protected (encrypted, authenticated, or both) in tunnel mode. The packet is then encapsulated by the IPsec headers and trailers. Finally a new IP header is prefixed to the packet, specifying the IPsec ...
