[clarification]: 'permit from any to any established' on ipfw passes packets with ACK or RST and is used on non-stateful firewalls to permit packets which are part of an active connection. Direct equivalent I think would be to have two pass rules for R/R and A/A, but it would be unusual to do this in PF without extraordinary circumstances.
