Umm.. broadcasts don't route which is probably why it doesn't work. Your basically trying to use iptables as a bridging mechanism where you really need a bridge. If the rule didn't work and there is no p-o-m to do something funky like this then I think your out of luck.. but I might be wrong..

I need to do something like ipportfw does: ipportfw -A -u 192.168.4.255/699 -R 192.168.2.255/699 which forward all the broadcast on network 4 for port 699 to network 2. I have something like this for iptables: iptables -t nat -A PREROUTING -p udp \ -d 192.168.4.255 --dport 699 \ --to-destination 192.168.2.255:699 But it didn't work. Anyone can give me some pointers ?? Thanks in advance. Rommy
