Can't ping my Windows 2003 R2 server from the internet.

My PC has two network cards... One is an onboard gigabit connected to my
LAN. The LAN is connected to a router, as are other PCs on my LAN. The
router is connected to a cable modem. The second NIC is a 10/100mbit PCI
card connected directly to another cable modem.

The GigE NIC is hardcoded to an IP on my private network with the following
settings:
IP: 10.0.11.16
Mask: 255.255.255.0
DNS: 10.0.11.1, 64.59.135.143
Gateway: 10.0.11.1
Gateway metric: 100 (previously auto)
Interface metric: 100 (previously auto)

The 10/100 NIC pulls a dynamic IP from my cable internet provider and
currently has the following settings:
IP: 68.145.38.197
Mask: 255.255.255.0
DNS: 64.59.135.143, 64.59.135.145
Gateway: 68.145.36.1
Gateway metric: auto
Interface metric: auto

The router is configured with my private network info on the LAN side and
dynamic settings pulled from my cable internet provider on the WAN side.
Currently configured as follows:
LAN side...
IP: 10.0.11.1
Mask: 255.255.255.0
Gateway: 10.0.11.1
WAN side:
IP: 68.145.78.218
DNS: 64.59.135.143
Gateway: 68.145.76.1

At this point I'm unable to connect to any services on the 100mb port, and
up until my last settings changes and reboot I was not even able to ping the
100mb port. My last change was to put the gateway and interface metrics on
the GigE port to 100 to ensure any remote traffic was going through that
interface, and to keep my local LAN traffic on the GigE interface. I
believe I should not have applied a metric to the GigE interface though.

At this point I cannot connect to any services on either port. Before my
last settings change I was able to connect the the remote desktop through
the GigE interface, but not any longer.

What I am trying to do:
- Any PC on my LAN, except this one, should use the internet connection
through the router.
- This PC should pass local LAN traffic over the GigE port only.
- This PC should pass internet traffic over the 100mb port only.

The PC's on my LAN are all hardcoded for the 10.0.11.0/24 network. Gateway
is 10.0.11.1. This appears to be working.

This PC does not consistantly pass it's internet traffic through the 100mb
port. I've tried removing the gateway IP from the GigE port, changing the
gateway metric to 100, and finally the interface metric to 100.

Windows firewall is enabled on the 100mb port, but allow ICMP is enabled, as
well as any ports that I need opened.

What should I be doing to make this work???

What IP address are you trying to ping from the internet? The private IP
(10.x.x.x)? This will not be possible because the private ranges are not
routable on the internet. They are called black hole IPs.

But about your config -

First of all, you have two gateways indicated on your PC. There must ONLY be
ONE gateway. You cannot have two gateways hardcoded. In your case, choose
the cable modem. Yes, all outside traffic communications will go thru that
cable modem.

Second, the firewall may not be allowing ICMP on that interface. Disable it
and give it a shot.

Third, you MUST allow ICMP pass through on the cable modem router/firewall.
This is NOT good practice. However you can pass traffic such as web, ftp,
etc, to your PC's internal IP address. This way to the outside world it sees
the cable IP address. You would connect to the cable IP address for these
services.

What are your intentions for access to your PC from the outside world? Keep
in mind cable companies are notorious for blocking all kinds of inbound
traffic to keep people from running servers and stuff. Plus their upload
speed is turtle slow at 768kbps. Their download may be fast, but upload is a
crawl. They won't tell you that part. That is why I got rid of my cable
internet access. They keep pleading for me to come back to them but I tell
them their service is slow and does not fulfill my requirements.
