ROS双ADSL相同网关加负载
1.设置PPPOELIENT 这个不用说了吧^_^ (注意：加的时候把 "Add Default Route"前面的勾勾掉，没勾掉的话去IP-ROUTE里把它删掉)
2.改PPPOE-OUT1和PPPOE-OUT2的名字：如改PPPOE-OUT1为WAN1 改PPPOE-OUT2为WAN2
改名字的脚本如下：
/int set [/int find name=pppoe-out1] name "ADSL1"
/int set [/int find name=pppoe-out2] name "ADSL2" |
3.在IP-ADDRESS里加IP地址
假如你的PPPOE-OUT1获得的IP为IP1(去掉子网掩码)，pppoe-out2获得的IP为IP2(去掉子网掩码)
/ip add add address=51.51.51.51 interface=pppoe-out1 disabled=no
/ip add add address=61.61.61.61 interface=pppoe-out2 disabled=no |
自动加IP地址的脚本如下：
:local 51.51.51.51 [/ip add get [/ip add find broa=0.0.0.0 interface="ADSL1"] address]
:local 61.61.61.61 [/ip add get [/ip add find broa=0.0.0.0 interface="ADSL2"] address]
:set 51.51.51.51 [:pick $ip1 0 ([:len $ip1]-3)]
:set 61.61.61.61 [:pick $ip2 0 ([:len $ip2]-3)]
/ip add add address=($ip1 . "/32") interface="ADSL1" comment= "ADSL1" disabled=no
/ip add add address=($ip2 . "/32") interface="你想要的名字2" comment= "你想要的名字2" disabled=no |
4.标记连接和路由、IP伪装、路由表添加
(这里用的是ROS官方的方法：伪装和路由的添加都是源自ROS官方的做法。具体解释请上官方查阅：http://wiki.mikrotik.com/wiki/Improved_Load_Balancing_over_Multiple_Gateways)
标记连接和路由
/ ip firewall mangle
add chain=prerouting in-interface="内网网卡" connection-state=new nth=1,1,0 \
action=mark-connection new-connection-mark=odd passthrough=yes comment="" \
disabled=no
add chain=prerouting in-interface="内网网卡" connection-mark=odd action=mark-routing \
new-routing-mark=odd passthrough=no comment="" disabled=no
add chain=prerouting in-interface="内网网卡" connection-state=new nth=1,1,1 \
action=mark-connection new-connection-mark=even passthrough=yes comment="" \
disabled=no
add chain=prerouting in-interface="内网网卡" connection-mark=even action=mark-routing \
new-routing-mark=even passthrough=no comment="" disabled=no
IP伪装
:local ip1 [/ip add get [/ip add find broa=0.0.0.0 interface="你想要的名字1"] address]
:local ip2 [/ip add get [/ip add find broa=0.0.0.0 interface="你想要的名字2"] address]
:set ip1 [:pick $ip1 0 ([:len $ip1]-3)]
:set ip2 [:pick $ip2 0 ([:len $ip2]-3)]
/ ip firewall nat
add chain=srcnat connection-mark=odd action=src-nat to-addresses=$ip1 \
to-ports=0-65535 comment="" disabled=no
add chain=srcnat connection-mark=even action=src-nat to-addresses=$ip2 \
to-ports=0-65535 comment="" disabled=no |
路由表添加
:local ip1 [/ip add get [/ip add find broa=0.0.0.0 interface="你想要的名字1"] network]
:local ip2 [/ip add get [/ip add find broa=0.0.0.0 interface="你想要的名字2"] network]
/ ip route
add dst-address=0.0.0.0/0 gateway=$ip1 scope=255 target-scope=10 routing-mark=odd \
comment="" disabled=no
add dst-address=0.0.0.0/0 gateway=$ip2 scope=255 target-scope=10 routing-mark=even \
comment="" disabled=no
add dst-address=0.0.0.0/0 gateway=$ip2 scope=255 target-scope=10 comment="你想要的名字2" \
disabled=no (这条也加标注的原因是为了后面的自动改网关脚本) |
5.到这里内网的机器已经可以上网了。下面的就是控制IP改动的脚本
先说改IP-ADD里的脚本
:local 51.51.51.51 [/ip add get [/ip add find broa=0.0.0.0 interface="ADSL1"] address]
:local 61.61.61.61 [/ip add get [/ip add find broa=0.0.0.0 interface="ADSL2"] address]
:local ip3 [/ip add get [/ip add find comment= "你想要的名字1"] network]
:local ip4 [/ip add get [/ip add find comment= "你想要的名字2"] network]
:set ip1 [:pick $ip1 0 ([:len $ip1]-3)]
:set ip2 [:pick $ip2 0 ([:len $ip2]-3)]
:if $ip1 != $ip3 do={/ip add set [/ip add find comment="你想要的名字1"] address ($ip1 . "/32") broa $ip1 network $ip1}
:if $ip2 != $ip4 do={/ip add set [/ip add find comment="你想要的名字2"] address ($ip2 . "/32") broa $ip1 network $ip1} |
改IP伪装和路由表
:local ip1 [/ip add get [/ip add find broa=0.0.0.0 interface="你想要的名字1"] address]
:local ip2 [/ip add get [/ip add find broa=0.0.0.0 interface="你想要的名字2"] address]
:local ip3 [/ip fir nat get [/ip fir nat find connection-mark=odd] to-addresses]
:local ip4 [/ip fir nat get [/ip fir nat find connection-mark=even] to-addresses]
:local ip5 [/ip route get [/ip route find routing-mark=odd] gateway]
:local ip6 [/ip route get [/ip route find routing-mark=even] gateway]
:set ip1 [:pick $ip1 0 ([:len $ip1]-3)]
:set ip2 [:pick $ip2 0 ([:len $ip2]-3)]
:if $ip1 != $ip3 do={/ip fir nat set [/ip fir nat find connection-mark=odd] to-addresses $ip1}
:if $ip1 != $ip5 do={/ip route set [/ip route find routing-mark=odd] gateway $ip1}
:if $ip2 != $ip4 do={/ip fir nat set [/ip fir nat find connection-mark=even] to-addresses $ip2}
:if $ip2 != $ip6 do={/ip route set [/ip route find routing-mark=even] gateway $ip2} |
添加任务
把上面的两个脚本添加到SYSTEM-SCRIPT里。命名为"change IP"和"change route"
/ system scheduler
add name="change ip" on-event="" start-date=jan/01/1970 \
start-time=00:00:00 interval=2s comment="" disabled=no
add name="change route" on-event="" start-date=jan/01/1970 \
start-time=00:00:00 interval=2s comment="" disabled=no |
