# --netif-ipaddr 10.0.0.2 is not a typo.
# It specifies the IP address of the virtual router inside the TUN device,
# and must be different than the IP of the TUN interface itself.
# This command assumes you have tor up and running on 127.0.0.1:9050.
# Of course, you can use any other SOCKS proxy instead.
