Restricting VPN Client access

Hi,

I am trying to create VPN Remote Access groups with limited access to our network. When I have the IPSEC rules allowing anything, it works without any problem. But as soon as I restrict the selected IP Pool to a specific resource, I am no longer able to log in. If I put a drop rule in following the above rule, I see the hitcount rise everytime I attempt to login. Any ideas what is being dropped not allowing me to login?

Thanks for your assistance,

Matt
 
Notes about my config:

The RA-VPN pool works without any issues. I am unable to login to the "test-deny" group. If I remove the restriction to the 64.1 device, I am then able to log in to the group. I am creating this config mostly through the PDM.
