FreeBSD firewall, nat, kernel

[regi at via-rs.net]

Hi,

I've just installed a FBSD 6.1 box and I want to install Firewall and NAT services.
The handbook Firewall chapter indicates to compile Firewall if you want NAT.
But, I could not find in the GENERIC file the IPFIREWALL options.

Do you have an idea ?

Thanks,
Regi
