[Bridge] physical interface on a bridge
...I am writing a dhcp server and need to know what real interface the dhcp re=
quest packet came from. An acceptable solution would be to get the interfac=
e by the mac-address, but that can be faked so I would rather get the inter=
face by knowing where the data actually came from. Data is IP, UDP broadcas=
t.
I _could_ use raw sockets. The problem is when I do that, the program is us=
ing ~8% cpu on a 3.2ghz xeon64 just reading packets without doing anything =
due to the amount of traffic passing through the box (~200mbit and increasi=
ng) so that doesn't look like a good idea.

*is* on a network computer A belongs to, the 10.30.1.0/24 network. So it
will do an ARP request (broadcast) to get the MAC address associated with
the 10.30.1.130 IP. The local Tinc gateway will ultimately (I believe,
Guus can speak on this with more authority than I can) perform the job of
proxy ARP to get the traffic to the destination on the other side of the
VPN.
