Сервер PPPoE на Ubuntu 14.04, Не работающей - Peer XXX, привел проверку Сессии CHAP к сбою

Я пытаюсь установить сервер PPPoE в своей системе человечности 14.04 для тестирования. Серверу и клиенту оба установили Ubuntu 14.04. Я следовал руководству с этого веб-сайта для установки сервера.

http://www.howtodoityourself.org/pppoe-server-how-to-do-it-yourself.html

Это - мой файл интерфейсов:

# The loopback network interface
auto lo
iface lo inet loopback

# The WAN network interface
auto eth0


# The LAN network interface
auto eth1
iface eth1 inet static
        address 192.168.1.254
        netmask 255.255.255.0

Мой сервер имен:

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 127.0.1.1
nameserver 8.8.8.8
nameserver 8.8.4.4

Секретный файл парня:

# Secrets for authentication using CHAP
# client    server  secret          IP addresses
"russo"     *   "1234"          192.168.1.1

Файл Параметров сервера PPPoE:

# PPP options for the PPPoE server
# LIC: GPL
require-chap
login
lcp-echo-interval 10
lcp-echo-failure 2
ms-dns 8.8.8.8
ms-dns 8.8.4.4
netmask 255.255.255.0
defaultroute
noipdefault
usepeerdns

IP-адреса объединяют файл:

192.168.1.1-20

Затем, когда я выполняю сервер PPPoE путем выполнения следующей команды:

sudo pppoe-server -C isp -L 192.168.1.254 -p /etc/ppp/allip -I eth1

и установка NAT

sudo iptables -t nat -A POSTROUTING -s 192.168.1.0/24 -o eth0 -j MASQUERADE

затем я соединяю свой клиент, использующий команду

sudo pppoeconf

на стороне сервера это - то, на что похож мой netstat:

mr@OptiPlex-760:~$ netstat -pr

Это - часть файла системного журнала:

На моей стороне клиента, если я проверяю plog, я вижу:

И это - мой netstat - PR:

Я не уверен, что я делаю неправильно. Любые предложения высоко ценятся.

Это - ifconfig-a результат стороны сервера (вначале):
