udp broadcast from one subnet to another thru a linux router
 

hi. i have a linux machine configured as a router. the two different subnets on either side of this router are able to communicate.
on one subnet is an application which sends out information on udp broadcast. how do i get this broadcast to reach the other subnet? no firewall is running on either card. ip forwarding is enabled. file sharing on windows is happening across the network. linux distro is mandrake 10 kernel 2.6

I don't know the answer to your question however I know this feature is called "helper-address". I thought knowing this could help you narrow your search...
