Version-Release number of selected component (if applicable): firewalld-0.2.5-1.fc17 Both (firewall-cmd --help) and (man firewall-cmd) suggest the syntax is firewall-cmd --direct ipv4 --passthrough ... but actually it seems to be firewall-cmd --direct --passhthrough ipv4 ... (I haven't tried the other --direct subcommands)
