Routing (cont)

froute = "fastroute" | "to" interface[":"ipaddr]
fastroute looks up the route to the destination in the kernel routing tables and forwards the packet without further processing (so outgoing rules are not matched)
"to" is equal to "dup-to", except the packet is not copied, but merely sent, without further processing
most notably, the TTL field is not decremented in the factroute, to and dup-to cases
be careful: it is easy to shoot yourself in the foot

froute = "fastroute" | "to" interface[":"ipaddr]
