   Hi Simon,   
      
   he setup is like this:   
      
   PC --->Wireless Network ----> Access Server ---> Cisco Router(doing   
   NAT/PAT) ---> Internet ---> VPN Server   
      
   I have full control of the Wireless Network, Access Server and the Cisco   
   Router.   
      
   Does that help?.
