I will setup gateway machine with 2 NIC:
eth0 for WAN and
eth1 for LAN. On gateway machine I'll install PfSense and setup Tor Proxy like for example here How to Set Up a Tor Proxy Server on pfSense. Client machine will be Windows.
Is it similar to Whonix Gateway + Workstation?
What kinds of leaks are then possible?
How to improve this setup without changing its parts?
