There's no need  to complicate this. The FreeBSD box will provide NAT 
for anything behind it, and if that includes the Wingate machine, fine, 
no problem. If the Wingate machine is in turn providing NAT for other 
machines, fine, no problem.

If Wingate is using, say 192.168. addresses for it's Natted network, 
use, say 172.16. for the FreeBSD internal addresses.
