VPN 3000 & DHCP IP allocation

[tjenkin2]

Hi,

I've configured a VPN 3000 to retrieve IP's from a DHCP server. Works fine - just had a query. When I look at the MAC address of IP that has been selected from the scope it comes up with the VPN MAC address + 9bytes on top. Does the VPN 3005 "spoof" MAC addresses for each user ?

During the initial tunnel negotiation, the client sends its host name to the concentrator, and the concentrator uses this in its DHCP request packet when requesting an address for the client. It is up to the DHCP server to dynamically add this host name into the DDNS server. Windows 2000 DHCP servers support this functionality.
