Few years ago, dean of our college decided to block lan network after 10PM because of “gaming impact attendance” blah blah.
Anyway, the way they implemented this is by blocking all traffic from/to ip addresses but not blocking tcp and completely forgot about ipv6 as it was not pretty new. So, I created a simple p2p chat Application which will work with ipv6. Only problem is that we had to share our ipv6 addresses with our friends which they have to maintain in contacts. It worked great until we figured tunneling to computer which is outside the network was much easier.
