setting NAT/VPN role for the first time

hello, I got a problems in setting NAT/VPN role in my windows 2003 Server.
iam trying to setting this role in small test enviroment consist of 1 Windows
2003 server + 2 windows XP Pro as a client.

Windows 2003 Server have 2 Network Card, 1 goes to ADSL Modem (DHCP Enable)
and another 1 go to switch.

NIC 1

IP DHCP = 192.168.1.2
Net Mask = 255.255.255.0
Default Gateway = 192.168.1.1

NIC 2 = 192.168.0.1
Net Mask = 255.255.255.0
Default Gateway = 192.168.1.2

Client 1
IP = 192.168.0.2
Netmask = 255.255.255.0

Client 2
IP = 192.168.0.3
Netmask = 255.255.255.0

Now, All client can access all share folder and resource in Server. However
none of the client able to access the Internet. Server can access All Client
Share folder/resource and also The Internet.

Where is the problems, why my client can't access the internet when server
can.

remote user able to dial in to VPN and use all network resource but VPN dial
in user also unable to use server internet resource.

Remove the default gateway from NIC2 on the server - this adapter should not
have a default gateway. All LAN clients must have a default gateway of
192.168.0.1
