Just look at your gmail spam folder. Gmail's antispam policy in not quite adequate.

Just create ordinary gif(4) or gre(4) tunnel between your two hosts and encrypt it with IPSec,
that will me more secure and much easier same time. Or, if you don't like gif/gre,
you maybe would like to use if_ipsec(4) native encapsulation for IPSec.
These *are* native options for FreeBSD. No reason to use more complex NETGRAPH schemes.
