Ato lihat ajah di sini dah:
• Install poptop
  # pkg_add -r poptop
• Buat file dengan isi berikut
  # ee /usr/local/etc/pptpd.conf

  debug
  nobsdcomp
  proxyarp
  localip 172.16.0.4
  remoteip 172.16.0.150-155
  pidfile /var/run/pptpd.pid
  +chapms-v2
  mppe-40
  mppe-128
  mppe-stateless

  # ee /etc/ppp/ppp.conf

  loop:
  set timeout 0
  set log phase chat connect lcp ipcp command
  set device localhost:pptp
  set dial
  set login
  # Server (local) IP address, Range for Clients, and Netmask
  # if you want to use NAT use private IP addresses
  set ifaddr 172.16.0.4 172.16.0.150-172.16.0.155 255.255.0.0
  add default HISADDR
  set server /tmp/loop “” 0177

  loop-in:
  set timeout 0
  set log phase lcp ipcp command
  allow mode direct

  pptp:
  load loop
  disable pap
  # Authenticate against /etc/passwd
  enable passwdauth
  disable ipv6cp
  enable proxy
  accept dns
  enable MSChapV2
  enable mppe
  disable deflate pred1
  deny deflate pred1
  set dns 24.26.163.24
  set device !/etc/ppp/secure

  # ee /etc/ppp/secure

  #!/bin/sh
  exec /usr/sbin/ppp -direct loop-in

  # ee /etc/ppp/ppp.secret

  #user #password #host
  user1 password *
  user2 password *

• Pastikan bahwa ip forward kebuka
  # sysctl net.inet.ip.forwarding=1
  atau apabila ingin diset default ketika startup
  # ee /etc/rc.conf

  gateway_enable=”YES”

• Aktifkan proxy arp
  # sysctl net.link.ether.inet.proxyall=1
  atau apabila ingin diset default ketika startup
  # ee /etc/rc.conf

  arpproxy_all=”YES”

• Lalu jalankan daemonnya
  # /usr/local/etc/rc.d/pptpd start

Tambahan:
Buat file /etc/ppp/ppp.linkdown agar dapat menghapus interface ketika disconnect.
# ee /etc/ppp/ppp.linkdown

pptp:
delete! HISADDR
iface clear

Udah deh …
