Not necesarilly better than gre(4), but you should also look into
gif(4), tun(4) and ppp(4)/ppp(8)/pppd(8)/pppoe(8). Last of all,
there's a new feature in ssh(1) that lets you tunnel traffic alongside
your ssh session (but this gives you a certain type of security).
On that note, what do you mean by "with pf without security" ? If you
pass the traffic required for the tunneltype you're using in pf(4),
it'll work. If you block the outer tunnel-traffic, your tunnel will
not work. Other than that, you can (of course) filter on the inside of
the tunnel. Please elaborate on this point.
