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
Although the answer has nothing to do with batman-adv or layer 2 services/setup you may want to look into a radius server for your network.
Batman-adv has no relation to how dhcp works.

if you don't wish batman to interfere with your DHCP requests I suggest to disable the gateway mode.

thanks for your feedback. I'd like to keep the gateway mode enable for regular clients. It is sufficient to disable the gateway-mode on the monitoring-node?

Absolutely. DHCP packets are manipulated by batman-adv only on the node where the packets enters the mesh.
