unfortunately, German only available at http://linuxrouter.minots.net/routing.html#forwarding btw. the activation does not reflect the fedora way replace the path /proc/sys/... by /etc/sysctl.conf and insert there # Controls IP packet forwarding net.ipv4.ip_forward = 1 to let your FC-Box act as a router. Also, in the shell type "man route" for information about the command how to set up your routing information. Usually, it should be enough, but even if you won't have information about iptables, remember doing necessary things also there, otherwise it won't work (except you don't let it run on your system).
