Hi,
thanks to all who have tried to assist with this matter of DHCP through
a wirless Bridge
(esp Erich & Tom) i'm having a hard time just giving up on this since i
know it's possible! In fact I have
reverted to my Bering 1.2 firewall and DHCP through my wireless bridge
magically works again. the only
thing different ( i think) is using the current dhcpd.lrp (doens't work)
vs dhcpd3.lrp (works).
perhaps theres some difference in these dhcp daemons? some other package
that i also need to run for
some reason? ( ex. i am running snmp under Bering 1.2 firewall but not
under Bering 2.3) can I run dhcpd3.lrp with
Bering 2.3 ? yes, i'm reaching for a usable work-around. I'd appreciate
any useful feedback/comments
that might help me work this out.
when I do the tcpdump on my firewall and dhcp works, i never see the MAC
address of
the client machines, just the bridge. The client sees the response and
gets the address just fine.
the daemon.logs show the request being honored just fine.
this has been clearly diagnosed as the problem (works when I force
cloning).
when it does not work, i see the bridge forwarding the request out to
the firewall
but when the dhcp server tries to send the reply to the MAC address of
the client, it's blocked
at the bridge.
p.s. I also made sure that dhcp was an option on my eth4 shorewall
interface that serces the wireless.

I then added a wireless bridge, which sees the AP fine and allows

provided it has a static ip. The mac filtering on the AP allows the MAC
address of the bridge ( 00:02:67:07:85:FE ) and does not
require allowing the mac address of the test machine
However, when I set my test machine to use DHCP, i get the following
behavior:
my machine connected to the wirless bridge tries to get an address via
DHCP and my firewall/dhcp server responds appropriately
however, the test machine never sees the ip address that is offered.
FWIW, I see the same results. I'm unable to get DHCP to work through a WET11
Linksys bridge (see http://www.shorewall.net/myfiles.htm).
