In ISA Server 2004 and 2006, it provides the VPN (Virtual Private Network) connection. I love using the VPN when I tried to remote and connected to my LAN at home. Of course, you might have to have Internet access. In ISA server, enabling VPN client is simply simple and easy.
Before a client can connect through VPN, you have to enable the VPN on the ISA Server. Also, You configure the ISA firewall’s VPN, such as how many client you need to connect the VPN. You need to consider the AD’s Group if it is in the Domain, and configure the DHCP pool.
I will continue this topic later.
