two NIC with 2 Different IP and Gateway

February 3, 2010 at 18:38:47
Specs: Windows XP
My department got 2 different network.
#1 Gateway is : internet)
#2 Gateway is : accounting w/out

How can i make 1 of the PC in my department
to possibly access both network at the same
time by using 2 NIC with the 2 different IPs
and Gateway?

Is it possible? how can i do that?

You cant have two gateways on the same system. windows will only ever use one, usually the first one it finds.

However, if network doesn't need Internet access then it doesn't need a gateway either and you can leave the gateway address blank.

Hi Stuart,

Thanks for ur reply.
But how can that network work if it doesn't have gateway address?coz that network is a WAN network(the server is at the other place,its not local server), just not available for internet access.

Ok..let say i use both can i point Internet Explorer to work with either one of the network?

The only solution in my mind is: Enable/Disable manually the NIC which i want/dont want to use.Is there any other solution?

If this computer is on the same subnet with the same mask as the server it still should work without gateway address.

A gateway address is only needed when connecting to completely different network and that usually involves a router.

Is this server accessed through a router? What is the physical connection between you and the server?

Either way, enabling and disabling is the only solution if you have two gateways. There is no way you can tell IE to use one gateway or the other.

Yeah, both network connected through the router.and the situation is like this:

Network #1:server--->WAN--->Router--->switch--->NIC1
Network #2:Internet--->modem--->Router--->switch--->NIC2

The Subnet mask for both network is also different.

How about if I configure the 'hosts' file on windows? what did u think? any idea?

improper topology.

should be:
Network #1:server--->WAN--->dual lan port Router--->switch--->NIC1
Network #2:Internet--->modem--->dual lan port Router--->same switch<>NIC1

otherwise you need another router between the two switches and this router in a different subnet/single gateway connects to a single nic.

I have 2 nics in one xp machine.

Network 1 is the primary network with a routable internet gateway.

Network 2 is the secondary network to which the second nic was added to access. This interface has no gateway assigned.

I have issues accessing network 1 for local dns request while the internet works fine. Everything returns to normal when I disable the connection to Network 2.

I smell a rat in how the TCP connections are made with the MS client!?!

No rats and what you are experiencing is understandable.

Network 1's dns is for the internet and that dns server knows nothing of your local network names.

Hosts file would be the way to go to address this issue since it does not appear you have an internal dns server on network 1.

How about a post of an ipconfig /all from this station for review?
