I have a DNS/IIS server with a public IP's. I configured DNS just fine,
can verify that it can send and receive email, etc. The 2nd NIC is
suppose to be on the internal side of my network, so the clients who are
NAT'ed can use the printer, and I can publish my web pages. I don't
recall how the IP structure is set up on the internal NIC so it will
talk to the rest of the nework, except to say that it had a IP something
along the lines of 192.168.1.253.

How can I set this 2nd card up so only the internal network has access
to it?

Thanks!

Steve
 
not sure the issue, but are they in the same subnet? can you ping? For more and other information, go to http://howtonetworking.com.

It is already like that to begin with.
 
No, they are on separate subnets. The external nic has a subnet of
255.255.255.248, the internal one has the default 255.255.255.0

Plus, I'm not totally sure what to put as the default gateway on the
internal card, that has the 192.158.1.253 address.

No, I can't ping other machines on the internal network.

Thanks

The gateway stays blank. You should also be using 192.168.1.253, not
192.158.1.253. The rest of your LAN is probably 192.168.x.x and you NIC on
this machine is misconfigured with 192.158.x.x,...therefore it can't contact
anything.
 
I had a typo. I actually set it to 192.168.1.253, and this time left it
with no gateway.

From my laptop, that is using a ip from a DHCP server (wireless access
point), I can't access the printer that is installed on the server.

On the public NIC I disabled file/print sharing, on the internal card,
its enabled.

What else might be the issue?
 
You haven't told us anything about how your LAN is designed and configured.
We need to know what we are dealing with in detail.
 
Ok, here goes:

I am running DSL, DSL modem goes to a switch that the external NIC is
connected to. The switch also has a connection going to a
firewall/router that is doing DHCP for the internal network.

I also have other servers on the internal network with static IP's
(database servers), along with a email server. The email server has a
public and internal card as well.

I have 1 Win2003 server running IIS/DNS, it is the machine with 2 NIC's.
1 NIC is multi-honed with 2 public IP's. The 2nd NIC should allow
all internal network communication.

Hope that helps
 
Well, some progress is being made. I can now browse shared folders on
the server via the internal NIC, but now I have a different problem.
Not sure if it would go in this group or not.

I have a FTP site set up to upload websites. I set it up to not allow
anonymous connections, added the users I wanted in the permissions,
including Admin.

I can't get in either remotely or on the server itself. I know the
password is correct though.....hmmmm.........

"In the permissions"? In the permissions where? FTP Services have no
"permissions" like that. It has Site Operators, but that isn't the same
thing. Permissions are granted using NTFS File System Permissions on the
folder(s) containing the contents.

If the external NIC and internal NIC don't connect to the same
hub/switch, and you're not running RRAS, then they don't have access.
Uncheck the TCP/IP Forwarding option as well.

"Can't get in" is pretty vague. Why not post actual errors and
descriptions of steps to reproduce the problem? Also post in the FTP
group for the best help. Make sure you test with the command line FTP
client so you can see the responses.
