Comment:
To fix this on the client side, all clients which are running in a LAN
which uses this netblock must treat this block as ‘internal’ for the
purposes of the ClientRejectInternalAddresses and
ClientDNSRejectInternalAddresses options. Thus, all clients must treat
this block as ‘internal’ (to avoid making different clients behave
differently).
To fix this on the relay/bridge side, a relay which detects that it is
running on a computer with at least one interface configured with an IP
address in this bogus block would need to (a) learn its address in a
different way, if necessary (e.g. if Address isn't explicitly set), and
(b) if ExitPolicyRejectPrivate has not been disabled, and the relay's exit
policy would otherwise allow exiting to this block, prepend a ‘`reject
198.18.0.0/15:*`’ line to its exit policy (both locally-enforced and
published).
Relays '''must not''' refuse to exit to this block unless either (a) all
currently-existing Tor clients are unable to connect to the public Tor
network, or (b) they publish an exit policy explicitly rejecting this
block.
I predict that this ticket will be bumped to 0.2.4.x.
