W2K Networking question

I have 2 network cards (NICs):

NIC1: Cable modem plugged into this one (DHCP allocated address)

NIC2: Plugged into hub (Static IP address: 192.168.0.1)

My problem is this: Internet explorer defaults to using NIC2 and therefore is not connecting to the internet. If I DISABLE NIC2, IE works ok, and then I can enable NIC2 again.

What do I do to remedy this situation?

Thanks for your help...

In IE go to tools, internet options, connections, lan settings, and check auto detect settings. Do you have ICS running on this box? if so go to tools, internet options, connections, shring and make sure the correct adapters are chosen to connect to the internet and the LAN

SysExpert

In addition, IF ICS is running, you may need to clean out the DNS IP of the internal NIC.

Routing should then take place properly.

I hope this helps !

What is ICS ?

stevenlewis

inernet connection sharing

stevenlewis

Yeah I can type LOL
ICS = internet connection sharing

jhattingh

ASKER

Thanks ;)

I haven't got ICS enabled, but I *am* using WinGate to do the same job...

jhattingh

ASKER

The thing is, it all works fine (including Wingate's ICS mechanism), just gets off to a bad *start*... :(

stevenlewis

try unistalling/disableing wingate, and use ICS (it's built in to w2k)

jhattingh

ASKER

I have tried it before, and found it difficult to set up.

Would my 2nd card become redundant if I used Win2K ICS?

stevenlewis

NO, the one card connected to the cable modem should have it's ip info set to auto
the one connected to the LAN should be set to
ip 192.168.0.1
mask 255.255.255.0
gateway blank and disable dns and wins
the client NIC (the other machine(s))
ip 192.168.0.(2-254)
maks 255.255.255.0
gateway 192.168.0.1
enable dns and use 192.168.0.1
disable wins
on the host (the one connected to the cable modem)
go to Inernet explorer, tools, internet options, connections, sharing and s
make sure the correct NIC's are chosen as connect to internet and connect to LAN

jhattingh

ASKER

Thanks for all the input, Steven,

One question before I start attempting that: I don't see sharing anywhere in the IE options - does this only appear when ICS is enabled?

stevenlewis

Yes it does, you have to enable ICS before the button shows

Have you tried chaning the binding order for the NICS ?
-Click on Advanced-> advanced settings in properties of network places & reverse the binding order.

ismart

Please could you open a DOS window and type ROUTE PRINT. This will print out your routing table. It sounds like that your machine is pushing all traffic to NIC 2 so it needs to be told that all traffic for Internet addresses should go to NIC 1.

You can change this using the ROUTE ADD command. If you post the results of the ROUTE PRINT then we can work out the correct routing you need for Internet access.

Try the following

route delete 0.0.0.0

then

route add 0.0.0.0 mask 0.0.0.0 62.31.227.1 62.31.227.115

then try and access the internet.

Thanks for the help:

I got:

route: bad argument 62.31.227.115

Could you explain what this means...? It would be great if I could understand it! I am not totally PC illiterate - being a C++ programmer, so don't be too daunted by the task!

AvonWyss

The solution is simple: remove the default route from the LAN adapter (in the properties of the atapter). The default route specifies where "unknown" traffic is to be routed, and therefore it must only be routed to the internat but not your LAN (the LAN are all known addresses).

jhattingh

ASKER

That makes sense - thanks for explaining it.

Could you tell me if this is how it should look?

FYI : I mentioed the DNS problem way at the beginning.

In addition, IF ICS is running, you may need to clean out the DNS IP of the internal NIC.

Routing should then take place properly.

I hope this helps !

AvonWyss

SysExpert, it was not about DNS but about default routes?

SysExpert

That's what I said :

In addition, IF ICS is running, you may need to clean out the DNS IP of the internal NIC.

<<< Routing should then take place properly. >>>>

I think what AvonWyss meant was that simply cleaning out the DNS IP wasn't the solution, even to the routing, since the solution has been to manually delete a route and then add a better one in it's place...

Maybe I'm misreading you folks.

I sure am grateful for all the time put into the question.

Thanks all, it's working great...
