# PCA Phobos for macOS (no Network Extension, no paid Apple account):
|
||||
# wireguard-go (utun) -> 127.0.0.1:13255 wg-obfuscator -> server UDP, or via udptcp -> server TCP.
|
||||
# + optional "home" tunnel (plain WireGuard to the home Keenetic) for 192.168.88.0/24 when away.
|
||||
# Usage (root): phobos on | off | status | auto | udp | tcp | ru on|off | import <phobos://...>
