I`v been trying and I can`t seem to get this to work. What I want to do is as following:
Route all hotspot traffic trough l2tp connection which I have rolled up towards my squid server.

Now, I`v been playing with mangle for last couple of days and it`s a no-go.
Anyone knows concept behind this? Mangle has never been used from my side and my knowledge of it is fairly limited (even tho I`v been reading a lot on this subject).

Any pointer would be more than welcome;

Thnx.
