VPN Pass through

I have the ASG running on my home network. I am a network admin and use CISCO's VPN client and other VPN software to connect to different clients from home. I can not get the traffic to "pass through" the ASG. I have seen on "cheaper" routers a simple check box for such a function. I am guessing this is some kind of Firewall rule.

Any detailed help would be appreciated...
