Firewall new connections from inbound probe requests

When two monitor processes connect, they become peers.  By default each
process can request probe connections with the other.

If you want to connect with a remote probe, but don't want those servers
to connect with probes in this process, call this method to firewall
those inbound probe requests.

Setting this will change the firewall value for all *new* connections.
Any existing connections will still accept incoming probe requests.
