Routing or access to the world with additional Windows IPs?

Question

Windows

There is one Ethernet network adapter with a white IP address (eg 192.168.1.1). There is also a white subnet (172.168.0.0/24). The gateway for the main IP is 192.168.1.254. The subnet is configured by aliases on the main interface.
Question: How can I make sure that when I connect via RDP to one of the subnet pool 172.168.0.0 (for example, to 172.168.0.1), I go out to the Internet with this IP 172.168.0.1, and not 192.168.1.1?
PS - The gateway for the pool is also 192.168.1.254.

Answer 1

There is one Ethernet network adapter with a white IP address (for example 192.168.1.1)

What is this white IP address?
It's not entirely clear what you want to do.
You will go out the Internet from the address of the gateway - what is the white address on the gateway, you will go out from this.
If there is no white address on the gateway, then you will be leaving the provider's gateway address.
There is no way to change this.
