Network routing with operating system

Salves 501 Reputation points


I have the scenario:

Server 1 on the network - Gateway
Server 2 on the network - Gateway
Server 3 on the network - Gateway

There is routing between networks using VPN Site to Site.

However, when I add a new vNIC on the virtual machine with the IP on the network, however windows says that a gateway already exists, I cannot reach the other network.

Is there something wrong with the windows routing?

Thank you.

    The text output from an ipconfig /all command will also help us understand your configuration.

    "windows says that a gateway already exists,"

    This warning message often occurs when one inadvertently assigns default gateways to more than one NIC. You can have only one default. If you want routing to occur on a network that is not the default network, you need to configure the other network with the route command.
