Internet with two network cards

Hello
I have a question for learning purposes and just plain curiosity.
Hope that is appropriate for this forum.
Let's say that I have a pc with two network cards which are each connected to routers that have internet access on them.
How does windows, browsers, etc decide which nic that it will use to access the internet. Does it assign a metric # for each interface and use that.
Thanks in advance

 

Windows will recognize one network interface as the default gateway, and that is the one it will use. You can manually create a routing table so that certain sites will be accessed through the other NIC. But everything that is not intranet and not listed in the routing table will go through the default gateway.

 

Hi,

It is worth adding that you can set up a default gateway on both NICs. However, only one of them will be used, and that is the one that is lowest in the routing table (the table is processed from bottom to top, so the lower one is processed first). I think the order is based on the binding order.

Use ROUTE PRINT at the command prompt to see you routing table.
