Help setting NAT on Windows 2003

Hello,

I have a server which is running as a DHCP server, a local DNS server to
serve local network (and forward to my ISP server for unanswered queries).
This server also serves as the primary box to connect to the internet. I
have 2 network cards, one which is connected to the ADSL modem and another
to the local switch.

I followed the wizard to setup NAT and everything works without a glitch.
From client computers I can do a name lookup given a name get the IP address
even for external address, this showing the DNS is working fine, but from
client computer I can't browse to external sites. Previously using ICS
client computer can use the Internet with no problem, so I know that the
network/DHCP settings are all fine. But when I switch to NAT the problem
occur.

Does anyone has any idea?

thanks,

Hadi

1. For the network card , for local switch the TCP/IP setting should be as
under. IP address (static): 192.168.0.1
Default Gate Way: NONE. (NO Default Gate Way.)

2. For network card for to ADSL modem:
IP address: what ever.it is
Degault Gateway.. the Default Gate way IP given by your ISP.

3. The NAT setting should be as under.
Click on IGMP tab:
Network Card for local switched should be set as Router .. Querier
Network Card for ADSL Modem shold be set as Proxy .... Up

4. Static Route:
Static Route should be added for Network Card for ADSL Modem
and the setting should be as under:
Destination Adrress: 0.0.0.0
Netwrok Mask: 0.0.0.0
(Setting above two to 0.0.0.0 will allow routing to
any destination.)
Gate Way - The Default Gate Way given by your ISP.

The client machines should use Default Gate Way: 192.168.0.1
(You can set this in DHCP Option too, so the client will get the
default gateway through DHCP , and on client machine leave the
default gateway blank.)

This is the basic setting, allowing access to all the clients.
For specific settings, like blocking clients, or allowing only
specific destnations etc. you will have to configure the routing
table, static route accordingly.

Sharad,

Thanks for you help but I still can't get NAT working on my box. I was
missing the static route before, added that in but still the same issue, DNS
resolve but no Internet. I notice however that my ISP doesn't give me a
default gateway setting. When I did ipconfig /all on my Windows 2003 server
it listed the default gateway for the PPP adapter as 0.0.0.0 and the default
gateway in my network card for the ADSL modem is blank.

So for the static route I added in the default gateway as 0.0.0.0 is this
the problem? Help my NAT is still not working ..

Thanks for your help

Default gate way 0.0.0.0 is definatley a problem.
Do you have a static IP for the network adapter for Internet connection? If
yes then try giving that IP as
gateway.

Hello Sharad and Bill,

Finally I had the chance to revisit this problem, so far we have been using
ICS because of the problem that I had with NAT. Unfortunately I still can't
get NAT to work

I think I have more information that someone here may have some answer about
it.

First I have 2 Network Card (I call them Internet and Intranet) AND an ADSL
modem. Intranet connect to the hub while Internet is connected to the ADSL
modem.

For Intranet I set the IP to: 192.168.0.1, Default Gateway: N/A

For Internet --> Automatically get IP

ADSL Modem --> Automatically get IP.

Now I have three network interfaces. The interesting thing is for the
Internet network card Windows 2003 automatically assign a local IP because
there is no information about it from the ISP, while the ADSL Modem is the
one that has a 'public' IP. Currently Windows assign 169.254.33.85
SubnetMask: 255.255.0.0 to this Intranet card.

so the IP config looks something like this:

C:\Documents and Settings\Administrator>ipconfig /all

I tried all sort of combination on the Default Gateway for Intranet and the
routing table with no luck so far. Please any suggestion?

Thanks,

Hadi

Yes we are using PPPOE with ADSL. What do you mean we are not logging-in to
the ADSL provider? On the server we don have Internet connection.

Thanks,

Hadi.

For a good description of using PPPoE with RRAS (especially if you are
using the Alcatel Speedtouch) go to
