## **左**架構：


### AR23301:

- 加 route:
$ sudo nano /etc/local.d/route_set.start

route add -net 10.233.0.64 netmask 255.255.255.192 gw 10.233.0.1
route add -net 10.233.0.128 netmask 255.255.255.192 gw 120.96.143.192
route add -net 10.233.0.192 netmask 255.255.255.192 gw 120.96.143.192

- 給予執行權限，開啟開機執行檔功能
$ sudo chmod +x /etc/local.d/route_set.start
$ sudo rc-update add local

- ip 偽裝
$ iptables -t nat -A POSTROUTING -o eth0 ! -d 10.233.0.0/255.255.255.0 -j MASQUSEADE

### AP23301:

- 加 route:
$ sudo nano /etc/local.d/route_set.start

route add -net 10.233.0.64 netmask 255.255.255.192 gw 10.233.0.1
