doubt about IPSEC - Freebsd 7

[Giulio Ferro]

I've noticed that in the kernel configuration IPSEC_ESP disappeared
from the options. It says that you just need device crypto and IPSEC.

Does this mean that with crypto and IPSEC I have all I need to treat
ESP like the old IPSEC_ESP option?

I'm having some problems right now setting up a vpn to complete phase 2,
(the error is no proposal chosen).
Since ipsec-tools uses the facilities in the kernel, I want to make sure 
that the
kernel provides everything racoon needs...
