OpenWrt配置单线多播的例子
先说明一下！此教程只适用于OpenWrt的Snapshot版和 Attitude Adjustment12.09版！其他版本请自行测试！此教程可能会涉及到一些破坏路由器配置文件的行为！请谨慎操作！一. 配置准备环境1.以上提到的两个版本的OpenWrt2.pppo.sh并发拨号脚本
3.配置路由器:TP-LINK 842nd v2
4.用到的插件:libc ip iptables iptables-mod-conntrack-extra iptables-mod-ipopt kmod-macvlan二. 配置部分1.安装辅助插件opkg updateopkg install libc ip iptables iptables-mod-conntrack-extra iptables-mod-ipoptopkg insatll kmod-macvlan
2.network文件的配置
vi /etc/config/network
config interface 'loopback'
option ifname 'lo'
option proto 'static'
option ipaddr '127.0.0.1'
option netmask '255.0.0.0'
config interface 'lan'
option ifname 'eth0'
option type 'bridge'
option proto 'static'
option ipaddr '192.168.1.1'
option netmask '255.255.255.0'
config interface 'wan'
option ifname 'eth1'
option _orig_ifname 'eth1'
option _orig_bridge 'false'
option proto 'pppoe'
option username 'xxxxxxxxxx'
option password '123456'
config interface 'wan1'#这步起都是模拟出来的WAN口
option ifname 'vth1'
option _orig_ifname 'eth1' #WAN口网卡
option _orig_bridge 'false'
option proto 'pppoe'
option username 'xxxxxxxxx'
option password '123456'
config interface 'wan2'
option ifname 'vth2'
option _orig_ifname 'eth1'
option _orig_bridge 'false'
option proto 'pppoe'
option username 'xxxxxxxx'
option password '123456'
config interface 'wan3'
option ifname 'vth3'
option _orig_ifname 'eth1'
option _orig_bridge 'false'
option proto 'pppoe'
option username 'xxxxxxxx'
option password '123456'
config switch
option name 'eth0'
option reset '1'
option enable_vlan '1'
config switch_vlan
option device 'eth0'
option vlan '1'
option ports '0 1 2 3 4'
此配置文件依据自己的情况进行配置三. 重启执行并发拨号脚本#!/bin/sh
#number是重拔次数
#n是几拔
#ok是拔上几次后退出拔号
#wait time
number=10000
n=4
ok=2 #这个可以任意修改！我这里只修改2拨后停止！
wait=20

保存该脚本！并把该脚本扔到/root文件夹下并赋予755运行权限；后在每个配置好的wan口在防火墙勾选wan；最后执行 /root/pppoe.sh
补充:1.由于路由器soc的瓶颈！所以脚本尽量不要设置那么多次数并发拨号！可能会造成路由器死掉！
2.脚本拨号的间隔可以根据自己的情况改变！
3.如果使用该脚本得停用mwan等插件！
