I am new to networking, my problem is: I have two internet connections in my company, so when one internet goes down, it should access from another – but it's not working: the Internet is connected to different routers and then connected to a switch. If I want to share Internet connections, what setting do I want to change on the computers or router?
I tried the following settings on the computers (Windows 7):
- Set the default gateway & preferred DNS as first internet
- Set alternative DNS as second internet
- Added the second internet connection IP in the "default gateway" option in the "advanced" tab of network adapter settings.
