belkin7231路由—双WAN负载均衡PPP0E拨号

看到论坛上已经有网友利用TOMATO实现是双WAN宽带叠加,也提供了教程可惜都是基于静态ip的
我也不懂! 幸好有boy516 这位DX的指点 勉强实现了!   稳定还是不行!尤其断线以后的问题
本文在belkin7231路由上 测试成功

首先到http://www.right.com.cn/forum/viewthread.php?tid=14465&extra=page%3D1 下载 已经编译好的TOMATO 刷上路由 后再复一下位

1.在WEB上 设置第一条 PPP0E线路 这个不多说了

2.telnet上路由 输入一下内容:

nvram set vlan0ports="1 2 3 5*"
nvram set vlan3ports="0 5*"
nvram set vlan3hwname="et0"
nvram commit
reboot

路由会自动重启

3.在WEB页面上 Administration —–>Scripts—–>WAN Up 输入以后内容 ADSL的帐号密码按实际修改   (如帐号:gzdslxxxx 密码:123456789) 保存重启

ifconfig vlan3 up
pppoecd vlan3 -u gzdslxxxx -p 123456789 -r 1492 -t 14

echo "Set default gateway…"

ip route change default equalize nexthop via $wan1_gateway nexthop via $wan2_gateway

echo "finished."

4.重启后TELNET上路由运行:ip rout
查看ppp0 和 PPP1

看到类似的提示第1,2行能获取公网IP 代表已经成功
# ip rout
218.19.168.1 dev ppp1 proto kernel scope link src 218.19.173.212
116.22.151.1 dev ppp0 proto kernel scope link src 116.22.151.61
192.168.2.0/24 dev br0 proto kernel scope link src 192.168.2.1
127.0.0.0/8 dev lo scope link
default equalize
        nexthop via 116.22.151.1 dev ppp0 weight 1
        nexthop via 218.19.168.1 dev ppp1 weight 1
default via 116.22.151.1 dev ppp0

这时你可以使用迅雷下载测试一下速度 在WEN页面上看看WAN (ppp0) 和WAN (ppp1)的流量
