Topic: Route broadcast (255) across subnets on different interfaces  (Read 1663 times)

I have two subnets on different interfaces using a static route between the two.  I can access clients across the two subnets using the direct IP but one of my applications requires me to "find" the client first.  The application uses a UDP broadcast message to 255.255.255.255 to discover the same app running on other clients I can configure the broadcast IP for instance 192.168.1.255 but even when I set the broadcast subnet to be the other network, it does not seem to go through the static route. 

The route looks like the following:

Interface  Network                 Gateway          Description
LAN          192.168.1.0/24      192.168.1.1      LAN -> LAB Route
LAB         192.168.10.0/24    192.168.10.1    LAB -> LAN Route

From the dim distant past, I seem to remember that Broadcast traffic is not routed/routable.

Hmm, that's probably why it's not working then.  Thanks for the reply.
