DHCP Question with USR8054 wireless access point / ZyXEL P652

Hi,
If I understand right DHCP only needs to be used on one divice? Then
which one and how..?
On the ZyXEL under LAN DHCP it is set as "Server", change it to anything
else and I no longer can connect to the Internet.
On the USR wireless access point LAN / DHCP it's also set as "Server",
disable it and again I'm no longer able to connect.
Looking at the firewall logs on the ZyXEL I keep seeing what's being
listed as an ATTACK <vulnerability ICMP(type:11, code:0)> from Source IP
192.168.1.33 to Destination IP 192.168.1.1 This takes place exactly
every 30 seconds. 192.168.1.33 is the wireless access point.

You need one DHCP server on your network, and no more.

Lets assume the zyxel is your wired router. In that case, you have it
set correct.

Is this an AP or a router? Either way you definitely need the DHCP
server disabled, it should then forward DHCP requests to the server in
the xyzel. Make sure a LAN port on the xyzel is connected to a LAN
port on the AP.

I'd say your Xyzel's firewall is configured wrong and is blocking your
AP from connecting or performing DHCP requests. Read the manual and
find out how to configure it right.

*shrug*
Then work it out yourself. Being rude to people who offer advice is a
poor way to go about getting help.

And I assume you consider all my other comments useless too.

FCOL, did they also leave out the chapter on configuring your
firewall, eg turning it off to eliminate that from the list of
possible problems? Did they also remove their phone number and support
email from the manual?

From wired or wireless clients? Never try to configure a wireless
router from a wireless client, for obvious reaons thats doomed.

Basically, you dont provide enough detail. How are the units connected
together? Which ports? What IP ranges? etc etc

FWIW I have an SMC and Actiontec router pair and they cooperate
perfectly, configured as I mentioned earlier. I've also tried a USR
router in place of the SMC, again worked fine.
