How to implement Juniper JunOS PPPOE configuration

1) Select interface fe-0/0/1 as the physical interface of the PPPOE dial-up interface and encapsulate it into pppoe

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

2) Configure the PP0.0 parameters of the PPPOE interface

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) Configure MTU With MSS

set interfaces pp0 unit 0 family inet mtu 1492

set security flow tcp-mss all-tcp mss 1350

4) Configure the address of the pppoe interface as negotiate- address

set interfaces pp0 unit 0 family inet negotiate-address

5) Configure PPPOE pap authentication

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

Passive CHAP authentication options are configured for unit 0 on pp0 interface.

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) Configure default route

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

7）Set zone

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 interface-based source address translation

Please change the internal network segment by yourself. Don’t copy them all. . .

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
