VPN Connection

Hi Guys,

i have 2003 installed on SYSA with 2 NIC (SYSA is a computer name) and SYSA is a Enterprise Domain innovation.com with an ip address 192.168.XX.X and also have an another system SYSB which is the client of that Domain innovation.com.

I have a BSNl Router WA1003A which is connected to the server 2003 with one NIC1 and another NIC2 is cross cabled with SYSB with Client.( I have configured a private network)
I have configured and enabled Routing and Remote access and configured VPN with the NIC1 which is connected to the Lan Port of that BSNL router.

I am not able to get the internet connection on both the machines and also enabled the NAT while configuring the Routing and Remote access

please help
