iptables 使用问题

[letitbesqzr]

学校必须代理才能正常上网,使用openwrt进行代理后用iptables转发,使用了以下语句:
iptables -t nat -A PREROUTING -i br-lan -p tcp -j REDIRECT –to-port 12345
12345端口为 redsock的端口 . 网卡信息如下:
br-lan Link encap:Ethernet
inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.255.0

eth2.2 Link encap:Ethernet HWaddr 00:0C:43:76:20:78
inet addr:10.1.224.34 Bcast:10.1.224.255 Mask:255.255.255.0

eth2.2 是上级路由分配的ip. 执行那-t nat -A PREROUTING -i br-lan 后,内网的主机就能自动经过代理上网了..但是路由器本身不能连接外网,请问该怎么写iptables语句实现让路由器本身通过代理上网

iptables -t nat -A OUTPUT -i br-lan -p tcp -j REDIRECT –to-port 12345
