Firewall > Rules > Loopback (see attached image)
I understand in general why the comment "No Loopback rules are currently defined. All incoming connections on this interface will be blocked until you add a pass rule. Exceptions for automatically generated rules may apply." appear on all Firewall > Rules pages. I have reviewed most other automatic rules and they pretty clearly only addressed a subset (and what appeared to be a relatively small subset of the potential traffic). However; in this case given the specific loopback automatic rules (and my newbie comprehension of their meaning) the first and second automatic pass rules seem to handle everything I believe exists (especially the second automatic rule my interpretation of the first is some special handling for some IPv6 traffic I will not have). Could the generally appropriate comment noted be considered confusing in this case, in that the exception may be total if I comprehend the second automatic rule correctly? If there are cases not covered by the provided automatic rules what might they be?
