Socks5:

Linux(pcap&rawsocket):
sudo ./phantomsocks -device eth0 -socks 0.0.0.0:1080

Windows(windivert):
phantomsocks -socks 0.0.0.0:1080

macOS:
./phantomsocks -device en0 -socks 127.0.0.1:1080 -proxy socks://127.0.0.1:1080

Redirect:

Linux(pcap&rawsocket):
iptables -t nat -A OUTPUT -d 6.0.0.0/8 -p tcp -j REDIRECT --to-port 6
./phantomsocks -device eth0 -dns :53 -redir :6

Windows(windivert):
./phantomsocks -redir 0.0.0.0:6 -proxy redirect://0.0.0.0:6

Configure

  server=*          #domains below will use this DNS or proxy server
  ttl=*             #the fake tcp packet will use this TTL
  domain=ip,ip,...  #this domain will use these IPs
  domain            #this domain will be resolved by DNS
  ip:port           #this ip:port will send fake packet when creating connection
  method=*          #the methods to modify TCP

server:

  server=udp://8.8.8.8:53
  server=tcp://8.8.8.8:53
  server=tls://8.8.8.8:853
  server=tfo://8.8.8.8:53 #Linux
  
  server=udp://8.8.8.8:53/ecs=35.190.247.1
  server=http://hostname:port                     #http proxy server
  server=socks://hostname:port                    #socks5 proxy server
  server=ss://method:password@hostname:port       #Shadowsocks proxy server

methods:

  none              #no modification
  ttl               #the fake tcp packets will use the TTL you set
  w-md5             #the fake tcp packets will have a wrong md5 option
  w-csum            #the fake tcp packets will have a wrong checksum
  w-ack             #the fake tcp packets will have a wrong ACK number
  w-seq             #the fake tcp packets will have a wrong SEQ number
  w-time            #the fake tcp packets will have a wrong timestamp
  s-seg             #the first tcp payload will be very small
  tfo               #SYN packet will take a part of data when the server supports TCP Fast Open
  https             #domains below will be move to https when using http on port 80
  df                #the true tcp packets will not be fragmented
  ipv4              #domains below will only connect via ipv4
  ipv6              #domains below will only connect via ipv6
  proxy             #domains below will connect via above proxy server
