I have a Cisco 678 Router using NAT forwarded to the External interface of
my server with required ports open. I just purchased a Fortigate 50 and was
wondering how to set it up with my configs.

Should I use the Routers NAT and set the Firewall in transparent Mode with
the gateway of my server pointing to the Firewall. Or should I also forward
the same ports on my firewall as the cisco, leaving the Cisco to perform NAT
Also, essentially running NAT on both the Cisco and the Fortigate 50
Firewall. Would NAT on both interfaces cause any problems or is it just
degrading performance?
