Cisco路由器拨号上网 设置

注：ISP和客户端相连的端口需要启用PPPOE、PPPOE enable、no ip address
ISP路由器配置如下：
vpdn enable
vpdn-group 1
accept-dialin
protocol pppoe
virtual-template 1 (调用虚拟模板1，类似环回口）

interfere F0/0
no ip add
pppoe enable

interface virtual-template 1
ip unnumbered loopback 0(借用还回口地址）
peer default ip address pool cisco
en ppp
ppp authentication pap(chap)
ip local pool cisco 202.1.1.2 202.1.1.10
username test password test

客户路由器配置步骤：
vpdn enable
vpdn-group 1
request-dialin
protocol pppoe

1.配置一个出口
interface E0/1
no ip address
pppoe enable
pppoe-client dial-pool-number 1

2.定义一个虚拟拨号口
interface dialer0
ip address negotiated
en ppp
dial pool 1
dial-group 1
ip mtu 1492
ppp authentication pap callin
ppp pap sent-username test password test

3.配置PAT
interface e0/0
ip nat inside
int dialer0
ip nat outside
access-list 1 permit 192.168.1.0 0.0.0.255
ip nat inside source list 1 interface dialer0 overload

4.配置DHCP
ip dhcp pool ADSL
network 192.168.1.0 255.255.255.0
default-router 192.168.1.1

5.配置静态路由
ip route 0.0.0.0 0.0.0.0 dialer0
