IP Conflict with ASA DMZ Interface

Hello there,

Anyone experience this? I've never seen this before ...

A host in DMZ segment is getting an IP conflict with the ASA DMZ interface itself. Any address assign to the host, always says IP Conflict.

Hello,

Turn off proxy-arp on the DMZ interface and see if that helps?

sysopt noproxyarp DMZ

regards,
