Not sure how much experience you have with FreeBSD.  I got this setup working
at home.  Which version of FreeBSD are you running?  Is your dual-NIC box set
to forward IP packets?  Is other words what is the value of the command

sysctl net.inet.ip.forwarding

This kernel variable should be set to 1

 sysctl net.inet.ip.forwarding=1

To make this change happen at boot up, I think you need
gateway_enable="YES" in your /etc/rc.conf file.

Hope this helps
Dany
