I know it definitely can be done with Cisco routers since those are the most
commonly used, but I generally have not been in charge of configuring them
so I could not give the details on how to set it up.

This is a short report. Have really been looking around but no success in UDP-routing of directed broadcasts. Found a small tool by Luigi Auriemma called sudppipe. I run it on the router and it seems to work fine. Just a drawback, it doesn't tell you that the machine is up. But if I try to remote control it after 100 s or so the machine can be remotely managed and that was my main purpose.

sudppipe stands for: Simple UDP proxy/pipe
usage: sudppipe 192.168.0.255,192.168.1.255,10.1.1.255 1762 1761
where 192* and 10* ar the subnets that receives the "magic packets" 1762 is the port on the server that sends the packet and 1761 the port the server listens on
