Build up NAT/VPN Role Server

Tech-Archive recommends: Speed Up your PC by fixing your registry

Hello, iam having a problems to setting up this role (refer topic) in windows
2003 Enterprise Server. I already trying more than 30 times with difference
setting also already follow lot of manual+tutorial on the internet including
MSCE E-book.

my first question;

is I need to run DHCP + DNS Server before i can setting up NAT/VPN role?
Currently iam not running DHCP + DNS Server.

my test enviroment is;

1 Server with 2 NIC
Dial up to internet using Windows PPPoE (1024Kbps download / 384Kbps upload)
2 Client running Windows XP Pro

This is Lattest Setting I had trial.

Primary NIC (DHCP Enable given by ADSL Modem)
IP = 192.168.1.2
Subnet = 255.255.255.0
Gateway = 192.168.1.1
DNS1 = 202.188.1.5
DNS2 = 202.188.0.133

Secondary NIC (Manual)
IP = 192.168.8.1
Subnet = 255.255.254.0
Gateway = Not Set
DNS1 = 202.188.1.5
DNS2 = 202.188.0.133

Client 1 (Manual)
IP = 192.168.8.2
Subnet = 255.255.254.0
Gateway = 192.168.8.1
DNS1 = 202.188.1.5
DNS2 = 202.188.0.133

Client 2 (Manual)
IP = 192.168.8.3
Subnet = 255.255.254.0
Gateway = 192.168.8.1
DNS1 = 202.188.1.5
DNS2 = 202.188.0.133

After Finishing Setting ALL NIC IP, iam back to the Server and run Manage
Your Server Configuration Wizard. Follow the adding NAT/VPN Role Wizard,
putting the adapter that have access to internet as Primary Adapter, All VPN
client will ge connected to Secondary NIC and also selecting Secondary NIC as
a share Internet Adapter (That the only one adapter offered by the wizard).

After finish, iam restarting Server and also all clients. Than dialing to
the internet. Once connected iam testing all connection.

Server able to access Internet, LAN, Share Resource.

Clients able to access LAN, Share Resource but unable to access Internet.

Remote Client, Connected using VPN Connection able to access LAN, Share
Resource but unable to access Internet.

So can somebody which is expert in this role teach me the correct way to
deploy NAT/VPN Role.

Note I already testing this IP configuration.
