1）选择接口fe-0/0/1作为PPPOE拨号接口的物理接口，并封装成pppoe

set interfaces fe-0/0/1 unit 0 encapsulation ppp-over-ether

2）配置PPPOE接口的PP0.0参数

set interfaces pp0 unit 0 pppoe-options underlying-interface fe-0/0/1.0

set interfaces pp0 unit 0 pppoe-options idle-timeout 0

set interfaces pp0 unit 0 pppoe-options auto-reconnect 3

set interfaces pp0 unit 0 pppoe-options client

3）配置MTU与MSS

set interfaces pp0 unit 0 family inet mtu 1492

set security flow tcp-mss all-tcp mss 1350

4）配置pppoe接口的地址为negotiate-address

set interfaces pp0 unit 0 family inet negotiate-address

5）配置PPPOE pap 认证

set interfaces pp0 unit 0 ppp-options chap default-chap-secret 12345678

set interfaces pp0 unit 0 ppp-options chap local-name szXXXXXXXX@163.gd

set interfaces pp0 unit 0 ppp-options chap no-rfc2486

set interfaces pp0 unit 0 ppp-options chap passive

set interfaces pp0 unit 0 ppp-options pap default-password 12345678

set interfaces pp0 unit 0 ppp-options pap local-name szXXXXXXXX@163.gd

set interfaces pp0 unit 0 ppp-options pap local-password 12345678

set interfaces pp0 unit 0 ppp-options pap passive

6）配置缺省路由

set routing-options static route 0.0.0.0/0 next-hop pp0.0

7）设置区域

set security zones security-zone untrust interfaces pp0.0

set security zones security-zone untrust interfaces fe-0/0/1.0

8）Interface based Nat 基于接口的源地址转换

内部网段请自行更改，别全部复制。。。

set security nat source rule-set trust-to-untrust from zone trust

set security nat source rule-set trust-to-untrust to zone untrust

set security nat source rule-set trust-to-untrust rule source-nat-rule match source-address 192.168.10.0/24

set security nat source rule-set trust-to-untrust rule source-nat-rule match source-address 172.16.0.0/16

set security nat source rule-set trust-to-untrust rule source-nat-rule then source-nat interface
