Advanced Routing and Traffic Control for Linux: GRE and other tunnels

Linux has 3 kinds of tunnels. They are: IP-in-IP tunnels, GRE tunnels, and non-kernel tunnels (such as PPTP). 1. Some comments about the tunnel tunnel can be used to implement many very unusual and interesting features. But if you have a problem with your configuration, there will be terrible mistakes. Do not point the default route to a tunneling device unless you know exactly what you are doing. Furthermore, the tunneling increases the protocol overhead because it requires an additional IP header. Generally it should be 20 bytes per packet, so if the MTU of a network is 1 ...

Technical explanation of IP virtual private network

IP Virtual Private network is a very complex technology, involving all aspects, the most critical of which is the tunnel technology. Simply put, the virtual private network is actually the data encapsulation of the enterprise network in the tunnel for transmission. Because the tunneling protocol is relatively complex, the virtual private network technology is complicated. The most typical of tunneling protocols are IPSec, L2TP, GRE, PPTP, L2F, and so on. Where GRE, IPSec belongs to the third-tier tunneling protocol, L2TP, PPTP and L2F belong to the second-tier tunneling protocol. The essential difference between the second and third-tier tunnels is that ...
