2 nics same pc again??

[Guest]

Have read the posts from a search for 2 nics but none answer my problem.

Have DSL from Qwest(192.168.0.1), running into Smoothwall router(red
192.168.0.2, green 192.168.1.1), smoothwall into 8 port switch and a 5 port
Gbit switch connected to that. ClarkConnect file server(10.1.1.1) with Gbit
card connected to Gbit switch. PC with onboard Gbit lan(10.1.1.3) for
fileserver access. Netgear 10/100 nic(192.168.1.78) for internet access.
Default gateway 192.168.1.1.

If I have both nics connected the internet nic nearly quits. Really slow or
no throughput. Fileserver access is fine. No connection between the 8 port
and 5 port switches results in same problem. Unplug or disable either nic and
I can get internet access(after changing the IP to 192.168.1.x of course)

Why can I not use both nics simultaneously? IP's are all manually set and
entirely different ranges.

Forgot to say I am using WinXP home.

Check that the NIC connected to the router has a default gateway and DNS
server address set for the router. The other NIC should not have a default
gateway as it isn't a route to other networks.

Then check t hat the router NIC is first in the binding-order (under
advanced network properties.)

Hi,

This doesn't have anything to do with your problem, but you obviously have a
DSL modem with a built-in NAT router. If I were you, I'd see about
switching the router feature off (they all let you do that), so that
Smoothwall's WAN interface can have a public IP address. It is not
essential that you do so for basic outbound connectivity, but dealing with
NAT twice will be a nightmare if you ever need to forward any incoming
connections, set up VPN etc.

smoothwall into 8 port switch and a 5 port Gbit switch
connected to that. ClarkConnect file server(10.1.1.1) with Gbit
card connected to Gbit switch. PC with onboard Gbit lan(10.1.1.3)
for fileserver access. Netgear 10/100 nic(192.168.1.78) for internet
access. Default gateway 192.168.1.1. If I have both nics
connected the internet nic nearly quits.

It _sounds_ like that should work. However, it also sounds like a lot of
unnecessary complexity. I'd take the fact it doesn't work too well (for
whatever reason) as a clue to simplify things. Why not reconfigure the file
server to live on 192.168.1.0 network and lose the second network card?

Why can I not use both nics simultaneously? IP's are all manually set
and entirely different ranges.

There may be something we are missing, but the issue could also be a
hardware conflict or something else unrelated to network configuration
alltogether.

I tried turning off NAT in the modem but could not get it to work. Set it
to bridged nat off dhcp off SW log in to ISP through PPPoA. Nothing worked. I
leave NAT on in modem, DHCP off no firewall, password protect the modem and
static IP's for SW PC's. SW does NAT. I'm not doing VPN. If I got static IP
from Qwest I think it would work.

I was just hoping to have 2 seperate networks----one for internet and other
for fileserver access and printing for laser printer. Keep fileserver away
from internet. I just thought it would be nice to try. At my work place tere
is a system set up that has 7 pc's with 2 dual nic in each(4 networks) all on
seperate subnets. I figured if they could do that I might be able to get 2
going.

This originally started when I installed a second NIC in my pc with a SOYO
mobo w/VIA chipset and could only get one(out of 5) pci slot to work. Card
was not recognized in any other slot. So I hooked up an NForce2 board to see
if that would work, and yes it did---all hadwre was detected and worked but
the second NIC was always super slow or not functioning. I'm back to one NIC
for now. And you are correct it is not all that critical.

Would that be under tcp-ip properties for the net connection? I'm not able
to find any choices for binding.
