[WireGuard] Using wireguard link as a proxy?

[Jason A. Donenfeld]

I usually do something like:

wg set wg0 peer ABCD allowed-ips 0.0.0.0/0
ip route add 0/1 dev wg0
ip route add 128/1 dev wg0
./tungate.sh proxyserver.wireguard.io

The tungate.sh script just ensures that proxyserver.wireguard.io is
reachable with the original route, and takes into account ifupdown
changes:
