Enable dual NICs to work on both the Intranet and Internet

Enable dual NICs to work on both the Intranet and Internet
Problem description: one computer has two NICs, one connected to the Intranet and the other connected to the Internet. The two NICs also need to work at the same time and do not need to be switched out when entering the Intranet, when connecting to the Internet, you do not need to unplug the Intranet network cable. What should I do?
Solution:

In fact, you do not need to write a route (that is, you do not need to use the route command.

You only need to configure the hops for the two connections to cancel the automatic hops,The value of the Internet hop is lower than the value of the Intranet hop.The Internet has a higher priority than the Intranet.

If the IP address of the router conflicts with the original Intranet IP address, change the IP address so that the Intranet and Internet are not in the same network segment.

You can modify the number of hops by clicking the "advanced" button on the page for configuring the local connection IP address.
