Hi,
Did anyone solved this scenario?
------------------
DHCP server -----------| ASA | ------------------------------ stations + PXE server
------------------
1) when DHCP snooping is off, everything works fine - PXE client receives address from DHCP server and also address of PXE server
2) when I turn on DHCP snooping, PXE client receives IP address from DHCP server, but doesn't know about PXE server
Modification of parameters 66,67 in DHCP server didn't help - client located PXE server, but stopped on loading bootwiz.sys and timeouted.
Thank you.

Hello,
preliminary question:
have you tried to trust the port where the PXE server is connected?
second question:
what switch model is involved and what IOS image is running?
I remember threads where some SW bugs related to PXE and DHCP snooping have been mentioned.
Having this information would help to narrow the search in bug toolkit tool.
I can confirm that there were issues for some switches with specific IOS versions
Hope to help
Giuseppe
