[Zyxel 8825] Enable NAT loopback

hitech95

My provider give me this modem/router but I have some services that must be accessible by both the LAN and WAN.

Is there a way to enable NAT Loopback on this device? Otherwise I'll have to move to another product.

Hi hitech
Would you please give me the full module ID, value is after VMG8825? and please provide the FW verison to me as well. That would be easier to check. Thank you.

After I checked it internally, it seems NAT Loopback is not supported on this device.
My suggestion is to contact your service provider to get help.

Is this option available on a not branded version of the Zyxel VMG8825-B50B?

@hitech95,

In my test with VMG8825-B50B Generic Firmware V5.13(ABNY.2)C0, it does support NAT Loopback.

I only add a port forwarding rule to map it to my LAN test server with a specific port number and then I can use a LAN client to access the server at the LAN side via the WAN IP of VMG instead of the LAN IP of the server.
