tar zxvf rp-pppoe-3.12.tar.gz
cd rp-pppoe-3.12/src/

# PPP options for the PPPoE server
# LIC: GPL
#require-pap
require-chap
login
lcp-echo-interval 10
lcp-echo-failure 2
ms-dns 61.139.2.69

2、配置用户名

vim /etc/ppp/chap-secrets

# Secrets for authentication using CHAP
# client        server  secret                  IP addresses
test             *       12345                     *

允许本地验证也就是修改options文件，将而来默认的lock改为local即可。

vi /etc/ppp/options    
#lock
local

运行pppoeserver

/usr/sbin/pppoe-server -I eth1 -L 192.168.115.100 -R 192.168.115.50 -N 200 &

配置NAT使客服端能够上网
echo “1” >> /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -s 192.168.115.0/24 -o wan -j SNAT –to 10.39.100.222
3、测试
windows xp客服端新建连接向导-连接到intelnet-手动建立-虚拟拨号系统PPPOE-用户名test密码12345
