Inbound NAT with Dynamic Public IP Address

Performing inbound NAT with a public IP address given by a DHCP server requires a different technique than when a fixed IP address is used.

Requirements:

• Dynamic DNS host (for example, dyn.com)
• The Dynamic DNS agent service running on a computer on the network

To create the NAT rule, go to Original Packet and enter:

• Source Zone The untrusted zone configured on the outside interface
• Source Address Any
• Destination Address Set a new address object and select "FQDN" as type, then enter the dynamic DNS host used
