I have a 5520 ASA running ASA Version 8.4(4)1, ASDM 6.4(9) that has remote access VPN enabled and hands off to a Windows 2008 R2 box handing out DHCP addresses. We attempted to make an IP address reservation based upon MAC address for a single end user. It looks like the ASA is not passing the unique identifier from the remote user down to the Windows server.
I have read a lot of forum posts where people are asking about reserving IPs for raVPN based on MAC addresses and it is only available using version 9 and IP V6.
Is this the case even if the ASA is not handing out the DHCP IPs?
