Raspberry Pi made into router

I have seen a lot of articles to make Raspberry Pi into a wireless AP, but what I want to do today is to make Raspberry Pi into a NAT-enabled router, I did this because I was on a business trip to Holland and found my bambook unable to access the dorm WiFi, Perhaps because the dorm wireless router is the way to authenticate WEP, in short, not even. Later decided to use Raspberry pi+ Arctic Starlight Wireless router to solve the problem. Ideas:"Wireless Router"-----"wireless network card--raspber

), they are also applicable to both IPv4 and IPv6. In other words, IPv6 uses the same technology as IPv4 to solve QoS problems. Without IPv6, the service quality will be guaranteed 。 (2) security assurance. Both IPv4 and IPv6 use the IPSec protocol to provide security assurance. The difference is that IPv4 has optional requirements on IPSec, IPv6 requires only IPSec. However, IPv6 only requires implementation and does not require all applications to use IPSec, second, the use of both products w

Compared with the traditional distance vector routing protocol, the connection status routing protocol has full topology information, so the routing loop is easier and the convergence speed is faster. Unfortunately, the connection status Routing Protocol relies on the network-wide broadcast (flooding)
