Hi David,
As it is ATM any IP with that range will match for all the rules for the 8 ports and the application cannot differentiate between them and it just returns the traffic to sender.
After this change the ports can be individually matched using the smaller /64 ranges for each port which are still within the given /48 subnet range (RFC5180).

I can send a v8 and CC stable if you think that’s needed.
Thanks,
Conor.
