VPN - Windows Server 2003 (NIC configuration).

 Hey,

The current environment is:
Router - external IP
Server 1 (Primary) WS2003 DC + DNS + DHCP
Server 2 (Secondary) WS2003 DC + DNS + DHCP
I'm going to add the new role VPN (RRAS-PPTP).
Server 2 (Secondary) has two NIC cards.

Currently it looks like this.

How to set up the NIC1 and NIC2.
I never set up vpn :(. Simple things make a lot of problems in the beginning.
