Depends on your end-goal. If your end-goal is to prevent local clients
from becoming supernodes, but allow them to access external supernodes,
then there are many solutions:
- NAT/firewall the local clients being the extreme
- Drop inbound first-contact packets to local clients
- Deep packet inspection for specific patterns identified by Salman

If your intent is to listen-in on supernode communication, or
traffic-shape it etc., that may be harder.
