Hi,
I had the same problem, and the solution for me was fairly simple. I had
to add a line to my /etc/rc.d/rc.local file to load a second file:
#/etc/rc.d/rc.local
#
#
# This starts the ip forwarding
#
/etc/rc.d/rc.route
Then add a new file called rc.route to your /etc/rc.d directory, and have
the following in it.
#/etc/rc.d/rc/route
ipfwadm -I -f
ipfwadm -O -f
ipfwadm -F -f
ipfwadm -Ip accept
ipfwadm -Op accept
ipfwadm -Fp masquerade
That was it. Once I had that on, I was working. Good Luck.
Pete
