I want to point out a caveat to others: Proxifier != VPN
wireproxy's wg only forwards TCP and UDP. I am not sure how ICMP is handled. Other transports, though rarely used, won't be tunneled (and may leak, if not dropped).
Most importantly missing: DNS, which usually is handled over UDP (changing slowly now with DNS-over-HTTPS and some TCP resolvers). Without handling DNS requests via your proxy, you're still leaking information about yourself to the resolver you're using.
To clarify, UDP is not currently supported, but I intend to support it in the future. Incoming ICMP should be completely dropped, and outgoing ICMP is not supported.
