Network routing with operating system

Hi,

I have the scenario:

Server 1 on the 10.10.0.0/24 network - Gateway 10.10.0.254
Server 2 on the 172.16.16.0/24 network - Gateway 172.16.16.1
Server 3 on the 172.16.16.0/24 network - Gateway 172.16.16.1

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 172.16.16.0/24 network, however windows says that a gateway already exists, I cannot reach the other 10.10.0.0/24 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.
