  set iface down-script /var/etc/pppoe1-vpn/linkdown
  set iface idle 0
  set iface disable on-demand
  set iface disable proxy-arp
  set iface enable tcpmssfix
  set iface mtu 1500
  set ipcp no vjcomp
  set ipcp ranges 10.9.9.1/32 ippool pool1
  set ipcp dns 10.9.9.1 8.8.4.4

  set bundle enable compression
  set ccp yes mppc
  set mppc yes e40
  set mppc yes e128
  set mppc yes stateless

  create link template L pppoe
  set link action bundle B
  set link no multilink
  set link disable pap
  set link disable eap
  set link enable chap
  set link keep-alive 10 60
  set link max-redial -1
  set link mtu 1492
