[求助]bridge模式两路WAN跑真实IP并作http80分流应用??

b128777

使用bridge模式时如何让www80port使用另一条线呢?

WAN1: 61.61.61.0-63 Gateway: 61.61.61.62
WAN2: 62.62.62.0-31 Gateway: 62.62.62.30

ros
WAN1--------eth1----Bridge1-----eth2---WAN1--(LAN) (61.61.61.0-63)
WAN2--------eth3----+++++++------------单独跑 www80port

请教高手一个技术问题，router主机为叁张网卡ether1,ether2,ether3
使用bridge模式将ether1,ether2作为bridge1，主要用意客户端ip全不用改
再来当用户端上网www80时，可否使用src-nat切换为使用ether3上网呢?

已测试两叁天一直找不到问题点，有作到src-nat切换来源ip，但routeros
还是使用bridge1的网卡，传送至WAN1 router造就一直只送syn send讯息，
无法让它当进入RouterOS时，切换使用ether3的ip上网www80port？


:ROS Interface 设置

:ROS IP Address 设置
/ ip address
add address=61.61.61.61/26 network=61.61.61.0 broadcast=61.61.61.63 \

add address=62.62.62.29/26 network=62.62.62.0 broadcast=62.62.62.63 \

:ROS IP Routes 设置
/ ip route
add dst-address=0.0.0.0/0 gateway=61.61.61.62 scope=255 target-scope=10 \
routing-mark=main comment="" disabled=no
add dst-address=0.0.0.0/0 gateway=62.62.62.30 scope=255 target-scope=10 \
routing-mark=adsl comment="" disabled=no

:ROS IP Firewall NAT 设置
/ ip firewall nat
add chain=srcnat src-address=61.61.61.0/26 routing-mark=adsl action=src-nat \
to-addresses=62.62.62.30 to-ports=0-65535 comment="" disabled=no

:ROS IP Firewall Mangle 设置
/ ip firewall mangle
add chain=prerouting protocol=tcp dst-port=80 action=mark-routing \
new-routing-mark=adsl passthrough=yes comment="" disabled=no

在 ip route mark-routing adsl 也有设置正确了, mark-routing adsl 是设在ether3, 但RouterOS
还是往bridge1送连线端口80, 当然ip nat设置部份也是加入相对应的, bridge1中的网路是正常
只是当是端口80作分流的皆无法连线成功!

PS: mark-routing adsl 线路是有确定可以上网的, 使用ping + src-address测试的!

请教高手不知还有解决方式，谢谢!!
