雙網卡轉發:把eth0上的某個IP請求上網轉發wlan0上.
- 先清空iptabes;
iptables -F #注意該命令並不會清空其他表,例如NAT表等
- 在NAT表中添加轉發
iptables -t nat -A POSTROUTING -s 192.168.50.100 -o wlan0 -j MASQUERADE #將192.168.50.100的請求全部轉發到wifi上.
在9以下此時是可以上網的,但是在9上不行,通過調試發現少了gateway在route表裏面,所以用Busybox route -n查看然後添加默認網關
busybox route add default gw 192.168.10.1(your wifi gateway)
