I have a legacy application that was originally developed for use on a non-routed network. It makes use of broadcasts for various functions (primarily device discovery). We are now trying to deploy this application on a routed network and, of course, the broadcasts are not traversing the routers and this breaks the application. This runs on a private LAN, isolated from the Internet or any other network not under our control.
I have ip directed-broadcast enabled on each interface. I've also tried ip helper-address <subnet broadcast address>. These seem to work OK for a single subnet, but what I'd like to do is an all subnets broadcast (e.g., 192.168.255.255). At the ingress router, this should be replicated out every interface with a 192.168.X.X network (I think), but I don't see this.
Any suggestings how I can get an all subnets broadcast to work?
