internal local-local firewall rule

[Martin0]

Hi,

I have a some server software running on my computer.

I want to make sure only a specific (local) application can connect to the server api. I would like to create a firewall rule that achieves this.
I intend to make a packet rule to with action being "By application rules", but first I'm testing it with action "Block".

No matter what I do, the connection is not blocked.

I've specified Direction: Inbound, Protocol: TCP, Port: server listening port.

Then I've tried remote addresses: Subnet Addresses, Local Network

Also tried Remote Address: Any address and Local Address: Any address
 

I'm thinking maybe the firewall doesn't do local to local packet inspection?

RSVP

Thanks

Martin
