Getting private range on Wan dont want to double nat
I have a sonic wall as the router. (Not mine), it is giving me a natted 192.168.101.x ip address on my wan interface. On my Fortigate 100D i want to have a dhcp range of 172.16.0.0/22 for my lan interface. I do not want to double nat, is there a way to use the natting coming from the sonicwall and disable nat on the fortigate?
On fortigate you simply create a firewall policy from LAN to WAN without NAT enabled in it , which is essentially route mode . On sonicwall create a static route for 172.16.0.0/22 subnet with gateway as IP address WAN interface of fortigate .
