So is your machine actually configured to forward packets at all?
use ``sysctl net.inet.ip.forwarding'', if that is 0 please change it to
1 by doing the following: ``sysctl net.inet.ip.forwarding=1''. If this
works please dont forget to configure the option in /etc/sysctl.conf
Let me know what this does please.
