Repost: NAT problem in Windows 2003 Server

Reposting this item ...

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

Thanks,

Hadi,

I am not sure what all your problem is, but the 169.x.x.x
IP that is being assigned to your "Internet" NIC is the
Windows Networking Automagically assigned IP.

That is to say that it will assign an automatic
169.254.x.x IP to any NIC that is set to obtain an IP
from DHCP but is unable to contact a DHCP Server.

Does your ADSL Modem provide DHCP services? I would
imagine that it does, however it may be disabled.

I am not sure why you added the third NIC (it appears to
be for a dial up adapter, possibly a custom SLIP/PPP
modem?) or if it just "showed up".

I would probably do the following:

1) Make sure your ADSL modem has DHCP and is enabled
2) Make sure your "internet" NIC is set for DHCP and then
restart the machine. If it still gets a 169.254.x.x
address, then find out what the default DHCP scope is for
the ADSL modem and assign a static IP to the Internet NIC
in that range (i.e. 192.168.10.x).
3) Remove the SLIP/PPP device if you don't need it
4) Re-enable ICS on the "Internet" NIC

Remember: If the ADSL modem/router provides DHCP then it
is also performing NAT for your outbound traffic.
Additionally, if you have enabled ICS on your server and
placed it between your clients and the Internet then ICS
is also doing NAT...Therefore your Natting Nat! Not
illegal, and your probably doing it so you can manage
internet access for your users. However, ICS doesn't
provide much "features" for protection or filtering,
etc. But for a small office it should suffice.

Good Luck, and I hope this helps!

Regards,

Tim

Yes since my Internet NIC is connected to my ADSL modem I assigned automatic
IP address and since there is no DHCP to contact Windows assign that IP to
it.

I don't think so since it's a normal ADSL modem that doesn't provide any
routing.

Correct, the third NIC is the dial-up adapter. That's the one that I use to
connect to the Internet (ie: double click .. enter user name/password etc,
isn't that the Windows way to do it?)

However I'm not trying to do ICS since I'm trying to set up VPN for the
remote user, VPN doesn't allow ICS/ICF to be turned on and it needs to use
RRAS instead. Maybe I should investigate why I have three NIC showing up ...

Thanks

Hmm finally I found a solution ... but this involve using a RASPPPoE. I use
RASPPPoE and bind that to my "Internet" network card and unbind the TCP/IP
there. I created a demand dial to use that network card to 'dial' to my ISP.
This solution works fine and now I have 2 NIC shown on the ipconfig.

BUT now I have problem setting up VPN because in the wizard it requires to
have 2 network cards which are bound with TCP/IP protocol! Arggh why does
this always happen to me!

Does anyone has a good guide on setting the VPN manually?

Thanks

You do not need two NICs to set up a VPN server. Use the remote access
server option in the wizard and accept the VPN option. (You can in fact set
up VPN on a server which is not even connected to the Internet! You can make
a VPN connection to it from other machines on the LAN, using the server's
LAN IP).
