2K3 Server - 2 NICS, 1 External, 1 Internal.. Here's my problem...

My last message disappeared from the newsgroups, so here's an updated
one...

I have 2 NIC's in 1 machine..

NIC 1: (ipconfig /all information)
Host Name: webmain
Primary Dns Suffix: mydomain.com
Node Type: Broadcast
IP Routing Enabled: Yes
WINS Proxy Enabled: Yes
DNS Suffix Search List: mydomain.com

Physical Address: MAC Address
DHCP Enabled: No
IP Address: 206.126.135.143 through 206.126.135.135
Subnet Mask: 255.255.255.0
Default G/W: 206.126.135.1
DNS Servers: 205.182.224.5 & 205.182.224.10

This NIC is plugged Directly into the back of Port 1 of my 4 Port DSL
Modem, and does nothing but serve our 3 Websites to the outside world.


NIC 2: (ipconfig /all information - summarized)
IP Address: 192.168.0.75 through 192.168.0.79
Subnet Mask: 255.255.255.0
G/W: 192.168.0.1
DNS Servers: 205.182.224.5 & 205.182.224.10

This NIC is plugged into the back of my 8 Port BEFSR81 router, so that
it can server intranet information to the inside world. The router is
then plugged into Port 2 on my 4 Port DSL Modem.

The problem I have is that when the 2nd NIC card is installed and
enabled, all my internal machines can see intranet information, and
can see the websites via NIC1's IP Address. HOWEVER, if someone from a
remote location tries to goto www.mydomain.com, the IP address does
not respond. If I pull the 2nd NIC out, then www.mydomain.com responds
to internal and external requests. However, then I have no intranet
information.

Any help would be appreciated!

What happens if you remove G/W: 192.168.0.1 from NIC 2?

I believe before, I left the G/W and DNS Servers out of NIC 2, and I
couldn't cruise the internet at all from within the building. Or,
maybe I just left the DNS servers out. I don't remember. Will try!

Just as an update to this message, I got tot he servers today, and
re-installed the gigabit cards, and did as you said. Left the G/W out
of the IP, but included everything else (IP, DNS). This time, while
having both NIC's in the machine, they were also serving IIS to the
outside world, as we wanted, as well as having inside internet access.

I had to change the Subnet between the two cards, because I noticed
that when doing network stuff, it would just "grab" a card, and we
wanted all the internal stuff going down the gigabit, so I changed the
workstations to the 10.15 scheme, and everyone seems to be working
fine!

Thanx for all the help folks!

Here's what my ending result looks like...

IIS NIC Card - 100mb
DHCP: No
IP Address: 206.126.135.143
Default GW: 206.126.135.1
DNS: 207.182.224.5 & 207.182.224.10
Subnet: 255.255.255.0

Intranet NIC Card -1000mb
DHCP: No
IP Address: 10.15.20.10
Default GW: Empty
DNS: Same as above
Subnet: 255.0.0.0
