In all the vendor documentation I find, examples for setting up IPSec tunnels use some of the worst encryption possible.

When I wander from place to place, I don’t want to have to remember to connect to the right VPN.

Sometimes you need to setup a tunnel between different kinds of endpoints.

A few months ago, a friend asked me for feedback on what kinds of network technologies should be taught in school (college level).

I like IPSec because it was designed to bind 2 networks together from the beginning.
