ROS、双ADSL、NTH负载均衡实际操作设置.doc

建立PPP拨号，把其中一条拨号名命名为ADSL1，另一个命明为ADSL2，并把内网网卡命名为LAN，然后等待拨号成功，设置参考下图 拨号成功后，PPPOE会自动添加IP地址和网关,找到地址和网关，复制下来，替换到下面脚本中把A1IP替换成ADSL1的IP，A1网关替换成ADSL1的网关，把A2IP替换成ADSL2的IP，A2网关替换成ADSL2的网关.之后慢慢添脚本，添完成功后，把拨号的Add Default Route的勾去掉，看负载均衡是否可以正常工作！ 1.普通脚本设置/ ip firewall nat add chain=srcnat action=masquerade comment=3 disabled=yes / ip addressadd address=A1IP interface=ADSL1 comment=1 disabled=no add address=A2IP interface=ADSL2 comment=2 disabled=no / ip routeadd dst-address=0.0.0.0/0 gateway=A1网关 routing-mark=1 comment=1add dst-address=0.0.0.0/0 gateway=A2网关 routing-mark=2 comment=2add dst-address=0.0.0.0/0 gateway=A1网关 comment=3 2.添加NAT，NTH脚本/ ip firewall mangle add chain=prerouting in-interface=LAN protocol=tcp connection-state=new nth=1,1,0 action=mark-connection \??? new-connection-mark=1 passthrough=yes comment=A1 NTH disabled=no add chain=prerouting in-interface=LAN protocol=tcp connection-mark=1 action=mark-routing new-routing-mark=1 \??? passthrough=no comment=A1 NTH disabled=no add chain=prerouting in-interface=LAN protocol=tcp connection-state=new nth=1,1,1 action=mark-connection \??? new-connection-mark=2 passthrough=yes comment=A2 NTH disabled=no add chain=prerouting in-interface=LAN protocol=tcp connection-mark=2 action=mark-routing new-routing-mark=2 \??? passthrough=no comment=A2 NTH disabled=no/ ip firewall nat add chain=srcnat connection-mark=1 action=src-nat to-addresses=A1IP to-ports=0-65535 comment=1 disabled=no add chain=srcnat connection-mark=2 action=src-nat to-addresses=A2IP to-ports=0-65535 comment=2 disabled=no 3.同步NAT，ADSL动态IP，网关脚本:位置winbox-system-script 点“+ ”号，改name为sync，然后复制下面的脚本到source里:local assign-address:local new-address:local status:local x:set x 2:for i from=1 to=$x do={??? :set status [/interface get [/interface find name=(ADSL . $i)] running] ??? :if ($status=true) do={???? :set new-address [/ip address get [/ip address find dynamic=yes interface=(ADSL . $i)] address]???? :set new-address [:pick $new-address 0
