VPN Client to DMZ Network

[azsean]

Hi, I am running a Cisco asa 5505 , ver 8.2(1). I have security plus license which DMZ is unrestricted. After reading alot of documentations on Cisco support site and other forums, I just can't figure out why I can't access the DMZ network while connected to my network via VPN client. I can talk to the DMZ network from LAN, but not from VPN client. below is my config. if someone can tell me what I am doing wrong or what I need to do to get it work, I'd be grateful. Thanks in advance.

doesn't this defeat the purpose of having users on a DMZ?

Well it depends how the environment is setup. In my case, we are few developers who work from home and office. So want to access the DMZ network and LAN for development purpose. We don't have normal users. But I do agree with you.
