Do you mind or can you be a little more detail with this. Was it a duplicate mac address which never should happen but does from time to time (remember the old kingston flaw in the early 90's about 150,000 nic cards same mac). Or was it a duplicate ip address. I could see if it was a duplicate ip where someone has the same ip as the concentrator that would cause remote clients to be disconnected, but a duplicate MAC I have never seen a cisco device with a duplicate mac.
Just curious to exactly what happened. -----Original Message----- From: Umar Ahmed [mailto:[EMAIL PROTECTED]] Sent: Tuesday, November 19, 2002 4:10 AM To: [EMAIL PROTECTED] Subject: Problem Solved: Cisco 3005 VPN concentrator issues.
