Windows 10: Any low cost solution for using Windows as home NAT router ?

I've been a Linux & Mac user for my whole life and I have my own computers in office. Recently the upper-level decided to further enforce monitoring effort, by forcing all of us to install 3 different set of monitoring softwares on computer, otherwise the network access will be blocked. Needless to say, there are only Windows version available. As a full stack coder, I'm not going to change my coding workflow. I'm planning to set a spared old Windows PC as guise, to satisfy those control freaks.

Problem is, I've no idea how the monitoring software works; I don't know whether it's proactively connecting to some server, or passively listening to some TCP/UDP ports on the given static private IP address. I'm now using a cheap D-Link home router to share the network link to my two working machines, and I need to enable port forwarding for HTTP access to my woking machine, so I can't just put the PC behind NAT and set it to DMZ.

Instead, I need to setup a NAT server on Windows to share the Ethernet connection to another Ethernet NIC for two of my own computers. In other words, I need to replace my D-Link home router with a Windows PC.

I fully aware how to set up packet forwarding and IP masquerading on Linux system, but I've no idea how to do that on Windows. I tried to search on internet, but after few hours reading I can only find 3 different types of solutions, regarding this topic:

1. Set up NAT in Hyper-V. This is not what I wanted since I need packet forwarding between two physical NICs.
2. Set up TCP forwarding using netsh command, but I need to forward UDP too for my project under development.
3. Install Windows Server. Yeah it works but it costs $500+ for a minimal essential licensing.

Is there any other 3rd party tools for this ? I don't mind paying for software but $500 is a little bit too much.

Hi,

If your NAT type shows Moderate, this is a good state. However, you may still have issues communicating or playing with other people who have Moderate or Strict NAT settings. To open your NAT settings, you may follow the steps
