Hi @toraman53,
Based on NAT technology, I think, the start ip address and End ip address fields should be the range of the public IPs.
For example, you get a public IP address range from 123.1.1.10/24 to 123.1.1.20/24. Then the start ip is 123.1.1.10, and end ip address is 123.1.1.20.
By the way, this is the enterprise forum, and your product belongs to the customer product. You may find more professional answers on consumer websites:
