Hello.
I installed FreeBSD 4.2, default Kernel. I want to enable NAT through PPP to
connect to the internet through my other windows boxes. The fact is that i
can't make it work. I configures windows the way the manual told. Do I have
to configure / install anything else on my FreeBSD box for the NAT to work ?
My config files:
