IP Conflict with ASA DMZ Interface

[Gerard Gacusan]

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,

NT

I had the same problem and i removed proxyarp on the dmz interface on the firewall. Another issue i am experiencing right now is that my natted DMZ servers are unable to reach the internet. what could be responsible?
