If you want quick&dirty then 6to4 is not going to help you in most cases
anyway, as you are mostly landing behind a NAT, as such Teredo (miredo
on non-windows boxes) is a way out and there is of course TSP which can
run over TSP and AYIYA. For some magical reason I prefer the last ;)

Also note that is it is their network, they can filter all they want,
just like you do you in your own.

(How did you btw determine that it is filtered, maybe the 6to4 packets
are just not coming back from a broken relay somewhere, that is very
hard to determine)
