Another example of tunnel mode is an IPSec tunnel between a Cisco VPN Client and an IPSec Gateway (e.g ASA5510 or PIX Firewall). The client connects to the IPSec Gateway. Traffic from the client is encrypted, encapsulated inside a new IP packet and sent to the other end. Once decrypted by the firewall appliance, the client’s original IP

What is the difference between the Tunnel and Transport Tunnel mode: Tunnel mode protects the internal routing information by encrypting the IP header of the original packet. The original packet is encapsulated by a another set of IP headers. It is widely implemented in site-to-site VPN scenarios. NAT traversal is supported with the tunnel mode.
Transport and Tunnel Modes in IPsec - Securing the Network
network - OpenVPN Tap vs Tun Mode - Information Security TAP is basically at Ethernet level (layer 2) and acts like a switch where as TUN works at network level (layer 3) and routes packets on the VPN. TAP is bridging whereas TUN is routing. From the OpenVPN Wiki : Transport and Tunnel Modes in IPsec - Securing the Network In tunnel mode, the entire packet is inside the ESP header. The packet in Figure 6–3 is protected in tunnel mode by an outer IPsec header and, in this case, ESP, as shown in the following figure. Figure 6-5 IPsec Packet Protected in Tunnel Mode.
