1 服務端
(1) 安裝pppoe，安裝完成後，會有pppoe-server命令
yum install rp-pppoe
安裝完成後，會在動在/etc/ppp目錄下生成pppoe-server-options文件。
(2) 修改服務配置文件
vi /etc/ppp/pppoe-server-options
# PPP options for the PPPoE server
# LIC: GPL
# 認證方式爲chap, 還可以配置爲pap方式
# win7密碼是加密的，可能不支持pap，所以測試最好是chap
require-chap
login
lcp-echo-interval 10
lcp-echo-failure 2
(3) 修改配置文件 /etc/ppp/options
vi /etc/ppp/options
# local # local for chap
auth # auth for chap
lock # lock for chap
(4) 添加賬戶
(a) 若採用chap認證方式
vi /etc/ppp/chap-secrets
# Secrets for authentication using CHAP
# client server secret IP addresses
"test" * "12345678" *
(b) 若採用pap認證方式
vi /etc/ppp/pap-secrets
# Secrets for authentication using PAP
# client server secret IP addresses
"test" * "12345678" *
(5) 設置支持IP轉發
vi /etc/sysctl.conf
net.ipv4.ip_forward = 1 # 修改爲1
(6) 啓動pppoe
pppoe-server -I eth0 -L 192.168.11.101 -R 192.168.22.200 -N 10 -F
# -L 虛擬PPPoE接口，不是eth0的IP地址(可以不設置eth0的IP地址)
# -R 起始地址
# -N 地址個數
# -F 前臺運行，默認後臺運行
2 客戶端
2.1 win7 客戶端
(1) 添加pppoe客戶端，如果已經存在，則直接連接
(a) 打開網絡共享中心
(b) 設置新的連接和網絡
(2) 輸入賬號和密碼，開始連接
2.2 centos 客戶端
(1) 安裝 rp-pppoe 包
yum install rp-pppoe
(2)使用root用戶，執行 pppoe-setup 生成配置
pppoe-setup
# 按照提示輸入對應內容即可
