1. Cấu hình IP cho Router Juniper
[TABLE="class: outer_border, width: 700"]
[TR]
[TD]// Đặt tên cho Router
root> configure
root#set system host-name svuit-vSRX
// Cấu hình IP interface ge-0/0/0
root@svuit-vSRX#set interfaces ge-0/0/0 unit 0 family inet address 172.16.1.200/24
// Cấu hình IP interface ge-0/0/1
root@svuit-vSRX#set interfaces ge-0/0/1 unit 0 family inet address 192.168.10.254/24
root@svuit-vSRX#commit[/TD]
[/TR]
[/TABLE]
- Kiểm tra lại cấu hình vừa rồi
Hoặc
- Router ping ra internet chưa thành công. Vì chưa thực hiện định tuyến
- Cấu hình default Route trên Router Juniper
[TABLE="class: outer_border, width: 700"]
[TR]
[TD]root@svuit-vSRX# set routing-options static route 0.0.0.0/0 next-hop 172.16.1.254
root@svuit-vSRX#commit[/TD]
[/TR]
[/TABLE]
- Kiếm tra bảng định tuyến
- Và Router ping ra internet thành công
- PC và Router ping lẫn nhau chưa được. Vì int ge-0/0/0 được thuộc vùng trust nên không cho phép ping.
- Cấu hình interface ge-0/0/1 vào zone INSIDE (do bạn tự đặt tên) và cho phép ping
[TABLE="class: outer_border, width: 850"]
[TR]
[TD]root@svuit-vSRX#set security zones security-zone Inside interfaces ge-0/0/1 host-inbound-traffic system-services ping[/TD]
[/TR]
[/TABLE]
- Kiểm tra zones
- Như vầy PC và Router có thể ping lẫn nhau
- Mô hình

- Các PC trong LAN ping được tới Router Juniper
- Router Juniper cấu hình default route để ping được ra internet
- PC trong LAN truy cập internet thành công
