The two gates
Your packet passed both gates on the way in. Does the answer get back out?
One packet has to get past two gates: a gate on the machine that remembers who it let in, and a numbered list on the street that remembers nothing. Untick a rule on either sheet and the verdict updates at once. Watch the reply fail at a gate the request sailed through.
Nothing plays automatically. Toggle a rule, reorder one or change a setting, and the verdict below updates.
try this Open The reply nobody wrote a rule for, then untick rules on either sheet and read the hops under The packet.
