Have someone here been able to get WOL proxy to work?

Our routers block the WOL magic packet and we've been trying to use WOL
proxies as a workaround but so far it doesn't work.

I have a service request open with tech support for more than one month and
AFAIK the issue has been escalated in a few occasions and the last thing I
was told is that this issue might be a bug in ZCM so I was wondering if
others here are successfully using WOL proxies.

I know is not the network because I can use other tools
(http://www.matcode.com/wol.htm) from the ZCM server to wake up workstations
in other subnets.

I'm using ZCM 10.2.1 on Windows 2008
