How to connect Direct Access Client to the Corporate Network

Hi,

Currently working on Direct Access Server for the test lab with the below configurations,

1)DC, DNS, DHCP and ADCS on Server 2012R2,

2)Direct Access Servers on Server 2012R2 

3)Client on Windows 8

I have installed the above said infrastructure on Hyper V and MAC address spoofing is also enabled on the Direct Access Server for NLB purpose.

All configurations have been performed successfully, i need help  how i can connect windows 8 client machine to the Direct Access Servers. 

Thanks,

Nasir
