[B.A.T.M.A.N.] DHCP-Monitoring of Gateways

Hello,

we're running batman 2013.4, having multiple Gateways. For doing so, we'd like to monitor the availability of every dhcp-server on each Gateway.

I noticed: If DHCP-Packages (even unicast ones) that unicast DHCP-Requests / Discovery are unanswered, if -> they're sent locally on a gateway -> sent to a gateway not "chosen" (according to batctl gwl) by the monitoring host.

What's the best way of monitoring all DHCP-Servers? Is there a way to set up a monitoring node, that can reach all DHCP-Servers? If not, how can request an ip address locally?

Thanks, Greetz, Jan
