Using MPD5 for PPPoE/vlan

HiddenWolf · Apr 10, 2015

I switched internet providers to xs4all.nl fibre this week.

I am running a FreeBSD 10.1 server as a router and firewall, running pf, dhcpd and various jailed services. Previously, I got an IP over DHCP from my cable modem. xs4all uses PPPoE and various vlans to deliver internet, voice and tv.

I'm primarily concerned with the IP part, which means that I had to reconfigure my machine to connect over PPPoE and set up vlan6. I got it to work using ppp, but performance is really poor, 40/20mbits where I should get close to 100/100.

I got the advice to try using MPD, but I am out of my depth and a lot of the information I can find is in Russian, which I don't speak.

I used http://gjppp.home.xs4all.nl/vdsl-pppoe/ as a tutorial for the mpd.conf, link up and link down scripts, even though the user is using vdsl as opposed to fiber.

I've embedded mpd.conf, the link up script, and the relevant bits of rc.conf, and the output of mpd5. My apologies for the wall of text that follows. I did replace my IP's with 0.0.0.0*
Running mpd5 manually results in a 'parameter negotiation failed' error. I am hoping that someone spots the error or can tell me how to debug this.

Code:

## mpd.conf

startup:

default:

    load xs4all


xs4all:

    create bundle static B1

    set iface up-script /etc/mpd5/mpd-linkup.sh

    set iface down-script /etc/mpd5/mpd-linkdown.sh

    set ipcp ranges 0.0.0.0/0 0.0.0.0/0

    set bundle enable ipv6cp


    create link static L1 pppoe

    set link action bundle B1

    set link max-redial 0

    set link mtu 1492

    set link keep-alive 10 60


    set auth authname ****@xs4all.nl

    set auth password ****


    set pppoe iface vlan6

    set pppoe service ""

    open

Linkup:

Code:

#! /bin/sh

# Usage: mpd-linkup.sh interface



[ -z "$1" ] && exit 1



route delete        default

route delete -inet6 default



route add           default -interface $1 -mtu 1492

route add    -inet6 default -interface $1 -mtu 1492

ifconfig $1 mtu 1492



/etc/rc.d/pf restart



Start dhcp6c

killall -9 dhcp6c && sleep 10

cat << EOF | sed "s/INTERFACE/$1/g" > /var/tmp/dhcp6c.$1.conf

interface INTERFACE {

        send ia-pd 0;

};



id-assoc pd {

};

EOF



# Wait for ng0 to be set up before running DHCPv6

sleep 3

/usr/local/sbin/dhcp6c -c /var/tmp/dhcp6c.$1.conf -p /var/run/dhcp6c.$1.pid $1

Relevant bits of rc.conf

Code:

## Basic networking

You can do this without the use of mpd The following case employs XS4ALL FTTH (Fiber To The Home) with as (optional) extra a VAS IP range.

/etc/ppp/ppp.conf

Code:

default:
  set log Phase tun command # you can add more detailed logging if you wish
  set ifaddr 10.0.0.1/0 10.0.0.2/0

xs4all_ftth:
  set device PPPoE:re0vlan6    # replace re0 with your Ethernet device
  set authname xs4all@xs4all.nl
  set authkey 1234
  set dial
  set login
  add default HISADDR

/etc/rc.conf

Code:

hostname="routerZW"
gateway_enable="YES"

# We cannot use the default vlan interface syntax re0.6 since ppp does not
# support interfaces with a dot in the name.
ifconfig_re0="up"
vlans_re0="re0vlan6"
create_args_re0vlan6="vlan 6 up"

# Start PPPoE connection
ppp_enable="YES"
ppp_mode="ddial"
ppp_profile="xs4all_ftth"

# Firewall configuration is left as excersise to the reader
#
# Internal network
ifconfig_re1="inet 192.168.178.1/24 up"


# NAT on internal network
natd_interface="tun0"
natd_enable="YES"
natd_flags="-dynamic"

#
# Optional VAS VLAN configuration, to expose the VAS IP addresses 
# to internal network port this is seperated by VLAN tagging as I do not 
# like to  mix-up to internal clients by accident.
#
# Make sure to change this to your own VAS range.
# Leave this block out when not used.
#
vlans_re1="re1vlan6"
create_args_re1vlan6="vlan 6 up"
ifconfig_re1vlan6="inet 80.127.152.25/29 up"
