When you are not logged in to an external network, do the following:
Run first -> cmd
Then enter ipconfig to see that the gateway of this network segment is displayed as: ip behind the default gateway.
Next, enter:
Route -p adds 10.0.0.0 mask 255.0.0.0 *. *.*.*
*。 *. *. * Here is the address of the gateway queried before.
Enter again after success:
Route -p adds 202. 1 19.0.0 mask 255.255.0.0 *. *.*.*
After that, you can log in to the home page and ftp at the same time by dialing the Internet.
There is no need to download the so-called intranet tool.
This method is to permanently add the static route to the routing table of this machine.
All visitors to the local address go through the local gateway instead of taking the route of the external network.
So there is no need to switch between the two sides.
If it is not needed in the future, just delete the two routes that have been added.
Specific commands can be accomplished by using route deletion or route change.
At the headquarters, the network cable is plugged into the computer and connected to the school intranet.
