Hi experts,

I have tried to fixed this problem over last 3 weeks, but I still failed.
Please give me some help or some advice.

I try to set up a SOHO network at home. The network devices and computers
are as follows:

SpeedTouch usb modem
Win 2003 server, domain controller and NAT enabled.
LinkSys wireless router
My laptop

The SpeedTouch usb modem connect to the telephone line which access
internet(ISP dynamically assigns IP).
My win2003 server connects to the SpeedTouch usb modem. Win2003 server can
access internet. My win2003 server only has one NIC which connects to the
router. I use the router as a hub.That means I switch off the route and DHCP
functions.
My laptop connects to the router wirelessly.

I intalled the DHCP server in the win2003, so my laptop can get ip
dynamically. I also installed domain controller in my win2003. My laptop is a
member of my domain. I can logon my laptop from domain. I enable the remote
desktop on my win2003 server. So I could be able to logon win2003 server from
my laptop.

I enabled the NAT in the RRAS and set up a demand-dial which can set up a
connection to internet.

The problem is my client laptop can not access internet.

Win2003 ip is 192.168.0.1

ipconfig results as follows:

PPP adapter RAS Server (Dial In) Interface:

Connection-specific DNS Suffix . :

My client laptop ip is 192.168.0.11

ipconfig result as follows:

We have some issues with this settings. You should not have two default
gateways. So, just use Default Gateway . . . . . . . . . : 82.152.192.1 and
no 192.168.0.1 as gateway.

Also have you enabled the IP routing? These search results may help too.

Hi Robert,

Thanks for your reply. I tried to change the gateway, but it seems not the
case. But I found another issue. I can ping external ip address from my
client laptop. That means I can browse internet by ip not domain name. So I
doubt I use the wrong DNS. At the moment, I use DHCP to assign IP to my
client laptop and it gains IP and DNS setting automatically. The DNS which my
client laptop using is the DNS istalled in my WIN 2003 server. So How can I
change the setting to make the client access internet?

Many thanks

Excuse me? If you can ping external hosts but can't resolve names that
exactly means you're using the wrong DNS (or the DNS is wrongly
configured).

Make sure that the internal DNS can resolve external names: use a
forwarder.
