Thx for the tip Priscilla. I've tried both, pointing to the server and the broadcast address of the subnet that the server is on, with no luck. Actually, late yesterday TAC found a bootp bug "CSCdp36754" that may apply to my ios ver and may be stopping my udp packets. I'll try the upgrade and see if that help.
