Comment:
This ticket asked for a way to have a relay that can't connect to other
relays on some particular port. But that's just one case of relaxing
Tor's clique assumption, which is also required for relays that don't have
IPv4 addresses, and relays that can't reach a subset of other relays.
Further, we'll need to remove the clique topology assumption in order to
scale to a large number of relays without requiring the number of sockets
used on each relay to grow proportionally to the size of the network.
We don't actually know how to do this safely right now; it will take a
pretty big amount of design work. Naive solutions have the problem that
they would make it easier for an adversary to force users into compromised
paths by manipulating the network topology.
