Restrict Port forwarding from a single IP address

[bmwsandman]

I have the following router.

Model Name: MI424-WR Hardware Version: C

Firmware Version: 4.0.16.1.56.0.10.14.4

I have a port forwarding rule working. However its open to the world. I can't figure out how to define an Advanced Filtering rule to limit the port forwarding to a single Source ip address

I found the following post and tried the solution but it didn't work

Has anyone got this working? Any suggestions

After you have the port forwarding rule working correctly, create an Advanceed Filtering rule to restrict it to a single source address. do the following

I put my rule under the Broadband Connection (Coax) Rules

Sourced address: IP address & select Exclude

Dest Address: Any (do not put the internal ip address, this will not work)

Protocol: RDP (in this case)

Operation: DROP

this should allow your Source IP address to access the port forward run, but drop connections for any other external ip address.
