NAP with IPSec for Unix Servers

Hi All, 

We have configured the following Group Policies as per TechNet Article:Configure IPSec GPOs (http://technet.microsoft.com/en-us/library/dd314176(v=ws.10).aspx)

Three Group Policy objects (GPOs) are used to apply IPSec policies:

• There will be an IPSec boundary GPO for computers with NAP exemption certificates that request, but do not require, that incoming communications are authenticated with a health certificate.
• There will be a Windows 7 IPSec secure GPO for computers running the Windows 7 or Windows Server® 2008 operating system. The secure GPOs will require that incoming communications are authenticated with a health certificate.
• There will be a XP IPSec secure GPO for computers running Windows XP with Service Pack 3. The secure GPOs will require that incoming communications are authenticated with a health certificate.

My question is to access Unix Servers in environment. How can I put the Unix Servers in boundary Network/Secure Network? Do I need to install NAP Exemption Certificate or in there any other way? Windows machine is trying to connect to Unix Servers by using putty.

 Thanks & Regards,

Kedar
