While the 5550s were running the only Windows 2008 server on the network was running fine. The rest of the servers are 2003. After the swap the 2008 server has issued with the IP address, it has an entry in its own log saying that there is a duplicate IP address in the DMZ, but the offending MAC address is the ASA's DMZ interface address. The server guys deployed a 2003 server with the same IP address to test and it was working fine. Did any of you see this before?</P><P></P><P>Thanks</P> Mon, 11 Mar 2019 19:39:56 GMT https://community.cisco.com/t5/network-security/asa5580/m-p/1626944#M593401 balla-zoltan 2019-03-11T19:39:56Z Re: ASA5580 https://community.cisco.com/t5/network-security/asa5580/m-p/1626945#M593403 <HTML><HEAD></HEAD><BODY><P>Hello Balla,</P><P></P><P>Please make sure that you dont have any static (DMZ,DMZ) or something like that, if you still face the same issue and that static is not configured, please try to disable proxyarp on that interface,</P><P></P><P>sysopt noproxyarp DMZ</P><P></P><P><BR />Cheers!</P><P></P><P>Mike</P></BODY></HTML> Wed, 26 Jan 2011 02:14:46 GMT https://community.cisco.com/t5/network-security/asa5580/m-p/1626945#M593403 Maykol Rojas 2011-01-26T02:14:46Z Re: ASA5580 https://community.cisco.com/t5/network-security/asa5580/m-p/1626946#M593406 <HTML><HEAD></HEAD><BODY><P>Mike,</P><P></P><P>The removing of the proxyarp fixed the problem.
