Accessing a website on the same public ip as the source

onedelve — Mon, 03 Jul 2023 02:40:34 GMT

* new here so if posted incorrectly. don't kill me *

Im trying to access mywebsite.com that is on a local IIS windows server.

I can access it from Outside ( via Cell phone ) via a NAT Inbound Policy.

I need to be able to go to mywebsite.com from a computer that is on the same vlan as the webserver. I have not found any documentation on how to setup that kind of nat policy. Can someone please assist. It would be greatly appreciated.

If it is on the same VLAN, then how the traffic is switched/routed?

Does it go through the FW?

How about the DNS lookup status from the internal network? Are you expecting to get the public IP or the private IP?

Hi @onedelve ,

All valid questions that @akuzhuppilly is asking but it sounds like you're trying to set up U-turn NAT (accessing an internal resource when you're resolving the external address).

U-turn NAT is explained here:

DotW: U-Turn NAT Issue

How to Configure U-Turn NAT

Hope this helps,

Yes its on the same vlan. It does go threw the firewall.
