Detailed explanation-1: -Select the zone containing your web servers. Sophos Firewall looks up the matching DNAT rule for the traffic. It identifies the zone containing the translated destination, which is DMZ in this example. It uses DMZ as the destination zone when it matches a firewall rule.
Detailed explanation-2: -You can configure Azure Firewall Destination Network Address Translation (DNAT) to translate and filter inbound Internet traffic to your subnets. When you configure DNAT, the NAT rule collection action is set to Dnat.
Detailed explanation-3: -To add a NAT rule manually, select Add NAT rule and then select New NAT rule. To create destination NAT rules and the related firewall rules automatically, select Add NAT rule and then select Server access assistant (DNAT).
Detailed explanation-4: -Firewall NAT policies collect rules to provide NAT address and port translation for source and destination addresses, including match rules for addresses and protocols, and translation rules for source and destination. You can attach a NAT policy at the device level, a route domain, or to a virtual server.
