[c-nsp] OT: Duplicate IP's.
We have VM's and now Desktops that are getting Duplicate IP errors on boot up when they have a static IP configured (and there is not duplicate IP). VMware says it's a ASA issue with Proxy arp. I have turned off proxy arp. Is there something else that may be causing these issues?

Yes make sure the VLANs are correctly expanded from the virtual NIC all the way through to the physical switch port.

Re: [c-nsp] OT: Duplicate IP's.
Scott, Can you post a sanitized output of show nat. I know you said you have proxy-arp turned off, but it does sound like a nat (inside,any) statement that's causing the issue. -ryan From: Scott Voll [mailto:svoll.v...@gmail.com] Sent: Monday, October 29, 2012 12:34 PM To: Ryan West Cc: cisco-nsp@puck.nether.net Subject: Re: [c-nsp] OT: Duplicate IP's. 8.4.4.5 On Mon, Oct 29, 2012 at 8:48 AM, Ryan West rw...@zyedge.commailto:rw...@zyedge.com wrote: ASA version? -Original Message- From: cisco-nsp-boun...@puck.nether.netmailto:cisco-nsp-boun...@puck.nether.net [mailto:cisco-nsp-boun...@puck.nether.netmailto:cisco-nsp-boun...@puck.nether.net] On Behalf Of Scott Voll Sent: Monday, October 29, 2012 11:40 AM To: cisco-nsp@puck.nether.netmailto:cisco-nsp@puck.nether.net Subject: [c-nsp] OT: Duplicate IP's.
