What do yuo mean by "broadcasts"? What protocol is being used? What
address are the packets sent to?

If, by broadcasts, you mean packets addressed to the "broadcast address" of
your subnet, it can't be done - you cannot route broadcast packets across a
router (that's why people use bridges). The only way it could be done is to
have a machine which understands the protocol, and is connected to both
networks, picking up the broadcast packets on one subnet, and then creating
new broadcast packets to send to the other network (and, of course, dealign
sensibly with the replies).
This, for example, is how you get Windows NetBios share browsing to work
across network boundaries - it's not pretty, but if broadcast packets are
what you're starting from then it's the only way.
