is there a way to offer ip addresses for clients based on mac
in packet (here 00:12:0e:34:e3:62) instead mac contained
in request (here 00:12:0e:34:e3:61)? override it in config?
i would like assigning based in source mac of packet instead
on mac in request in very rare case when they differs..
almost all client hw devices in our network have a same
mac in request as in source of packet but not all of them,
esspecialy appears some wireless adapters like this from
example below, which is from my real live...
