Note that libalias already has a flag PKT_ALIAS_SAME_PORTS (natd -same_port= s or ipfw nat config same_ports) to somehow change port translation rules. Please make your change conditional using new flag for new translation mode. --=20 You are receiving this mail because: You are the assignee for the bug.=
