Make multicast packets local-only?



The situation:

I have two computers, PC1 and PC2, each running multiple multicast-
utilizing applications (specifically, UPNP). Each app multicasts its
presence via SSDP (239.255.255.250), allowing other applications on
PC1 and PC2 to discover it.

My goal:

What I want to do is to prevent PC2 (and PC3, PC4, etc.) from
detecting multicast applications running on PC1. The PC1 apps must
still be able to detect each other, and also be able to detect
multicast apps on PC2.

Is this possible?
