DHCP Not Working:
It's easy enough to test. Unplug your ABS from the lan and see if
that's the issue.
I think Marc's right. I don't think you can segment your network
like that with the ABS. Put it in Bridge Mode and see if it works
then.
Yes, easy enough to test, which I did, with the same results.
Do you have the logging level set to "high" on the DHCP service? If
not, set it that way and see if you can see the clients requesting
addresses.
Look at the firewall logs: any denied requests on port 67/68? Do you
have port 67 available to subnet 0.0.0.0? Try disabling the firewall
altogether if you've not already.
What is the output of
ipconfig getpacket en0
when run on a client which is set to DHCP?
What's the switch config like?
HTH
-geoff
I thought that with nothing connected to the ABS LAN port, it would
leave the wired network alone. Logically, it would ignore DHCP
requests on the WAN port, yes?
Note: At one point whilst stopping and starting the service, I
noticed that a client Mac set for DHCP, but which had a self-
assigned IP, would get assigned an IP when I stopped and restarted
the DHCP service. Curiously, with an assigned IP, if I clicked the
client's 'Renew DHCP Lease' button, a self-assigned address would
result. It required stopping/starting the service again to get an IP
assigned again. It did this a few times, then stopped working
altogether.
So I'm back where I came in.
Question: Is there a way, via Server Admin, to disconnect a client,
that is, rescind the address assigned?
I ask because I changed one client with a dynamic address to use a
(different) manually assigned address but it continues to show up in
the DHCP service Client list. It even survived a server shutdown and
boot. This service unable to see that the MAC is not using the
assigned address (which makes sense) but it would be nice to be able
to remove the client from the list.
