16.4. Using PPP over Ethernet (PPPoE)

   Contributed by Jim Mock <jim@FreeBSD.org> (from node.to) 10 Jan
   2000.

   The following describes how to set up PPP over Ethernet, a.k.a, PPPoE.

16.4.1. Prerequisites

   There are a few requirements that your system will need to meet in
   order for PPPoE to function properly. They are:
     * Kernel source for FreeBSD 3.4 or later
     * ppp from FreeBSD 3.4 or later

16.4.2. Kernel Configuration

   You will need to set the following options in your kernel
   configuration file and then compile a new kernel.
     * options NETGRAPH

   Optionally, you can add
     * options NETGRAPH_PPPOE
     * options NETGRAPH_SOCKET

   although if this functionality is not available at runtime, ppp will
   load the relevant modules on demand

16.4.3. Setting up ppp.conf

   Here is an example of a working ppp.conf:
    default: # or name_of_service_provider
      set device PPPoE:xl1 # replace xl1 with your ethernet device
      set mru 1492
      set mtu 1492
      set authname YOURLOGINNAME
      set authkey YOURPASSWORD
      set log Phase tun command # you can add more detailed logging if you wish
      set dial
      set login
      set ifaddr 10.0.0.1/0 10.0.0.2/0
      add default HISADDR
      nat enable yes # if you want to enable nat for your local net

    papchap:
      set authname YOURLOGINNAME
      set authkey YOURPASSWORD

   Care should be taken when running PPPoE with the -nat option.

16.4.4. Running PPP

   As root, you can run:
    # ppp -ddial name_of_service_provider

16.4.5. Starting PPP at Boot

   Add the following to your /etc/rc.conf file:
    ppp_enable="YES"
    ppp_mode="ddial"
    ppp_nat="YES"
    ppp_profile="default" # or your provider
