I am going to deploy a network with multiple VLANs, i have been using cisco firewall but this time the customer is short on money so had to install DELL firewall there. Now the thing is that, I want to add multiple VLANs 2 or more and want to grant them access the internet, please correct me if i am wrong
1. I will have to create sub-interfaces for each vlan on switchport where i will connect Sonic-wall and configure that port as trunk & configure virtual sub interfaces on firewall (X0) LAN interface, ?
2. NAT policy , I have multiple subnets i want to create inbount/outbound NAT policy what is the best practise ?
