Controlling Two Network Card by LabVIEW

[spapasinon]

Hi,

I'm using LabVIEW 8.5 and Windows XP.

I am intending to use LabVIEW to control a PC with 2 network cards in it.

I want to send TCP/IP packet out from one network card,
and receive the packet from another network card.

Do I have to change the confguration of the XP system?
How can I assign those two different cards to send and receive individually?

Can anyone tell or suggest what to do for me

Thank you very much~ ^^

See this thread where Mark posts some good notes on networking.

You will have to adjust your masks so they can see each other.

Start by using "ping" to test connectivity.

You will not be able to directly prohibit the network cards from receiving or transmitting. You can define your network routes on the PC to route the traffic in the manner you want. Each network adapter will need to have its own IP address. NI's Internet Tool kit has a few issues, most notably the FTP VIs, when using multiple NICs. In addition, any DNS requests made will be routed to the primary network card. Windows determines which interface it thinks is the primary interface. From a code perspective using the native TCP or UDP VIs you will not have to do anything special.
