Kernel Option Question

["Martin Marconcini" <megadeth@millic.com.ar>]

Hi: i have seen that help (FAQ) says that there's an option called

option          IPFORWARDING

that: "Enables IP routing behavior. With this option enabled, the machine
will forward IP datagrams between its interfaces that are destined for other
machines."

However... i downloaded srcsys.tar.gz and I havent found that in GENERIC
But there are two interesting options
option          GATEWAY         # packet forwarding
option          INET            # IP + ICMP + TCP + UDP

Basically I need to remove IPv6 Support.

I though that by commenting this out it will be enough (#option
INET6           # IPv6 (needs INET))
However, when I boot the new no ipv6 kernel, I found out that pf is no
longer working!

(pppoe/internet works fine for localhost!), but pf is down.

If I reboot back with the bsd that exists on the CD (that is, the original)
it works again.

Now the question is, what might I be missing? Should ipforwarding option
exist?

Thanks in advance

Martin.
