Can't ping my PC 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.

What should I be doing to make this work???
 
In this case, the LAN NIC should not be assigned a default gateway. This
search result may help too.

Hi
What exactly you are trying to achieve, if you are using a Windows Client
(Not a server) OS like XP, or Vista there is No real functional use for
such arrangement.

Simple...

I want all the PC's on the LAN except this one to surf the internet through
the router.

I want this one PC to connect to the internet through its 10/100 card. I
don't want any traffic from this PC to affect internet bandwidth available
to the other PC's on the LAN.

I want all the LAN PC's to be able to access the files on this PC through
the GigE card.
If you want to use both Internet connections you should use a Dual WAN
Router.

I've got one and it's a piece of junk... It crashes with even only moderate
amounts of traffic. It ignores bandwidth settings for each port. I could not
get port forwarding to work properly.

That is what I thought... Getting rid of the gateway on the GigE port should
mean that only local LAN traffic flows, but it didn't seem to work that way.
I'll be trying this again when I get back to this PC.

Makes sense... Thanks!
 
Hi
The "lonely"computer connects to the Modem directly and would assume the
External IP on its 100Mb/sec. card.
The TCP/IP stack of the 100Mb/sec card should Not be bound to File Sharing.
The Giga card should be configured as part of the LAN, and bound to files
sharing.
The 100Mb/sec card should have lower metrics so when you start the Browser
it would be used for surfing.
