3单一网络中的3条互联网线路

Question

我要把3条互联网线路连接在一个网络中。

我使用Mikrotik RB750路由器，我将这个路由器配置如下：

/ip firewall mangle
add chain=input in-interface=WAN2 action=mark-connection new-connection-mark=WAN2_conn
add chain=input in-interface=WAN3 action=mark-connection new-connection-mark=WAN3_conn
add chain=input in-interface=WAN4 action=mark-connection new-connection-mark=WAN4_conn
add chain=input in-interface=WAN5 action=mark-connection new-connection-mark=WAN5_conn

add chain=output connection-mark=WAN2_conn action=mark-routing new-routing-mark=to_WAN2
add chain=output connection-mark=WAN3_conn action=mark-routing new-routing-mark=to_WAN3
add chain=output connection-mark=WAN4_conn action=mark-routing new-routing-mark=to_WAN4
add chain=output connection-mark=WAN5_conn action=mark-routing new-routing-mark=to_WAN5

add chain=prerouting dst-address=192.168.2.0/24 action=accept in-interface=bridge1
add chain=prerouting dst-address=192.168.3.0/24 action=accept in-interface=bridge1
add chain=prerouting dst-address=192.168.4.0/24 action=accept in-interface=bridge1
add chain=prerouting dst-address=192.168.5.0/24 action=accept in-interface=bridge1

add chain=prerouting dst-address-type=!local in-interface=bridge1 per-connection-classifier=both-addresses-and-ports:4/0 action=mark-connection new-connection-mark=WAN2_conn passthrough=yes 
add chain=prerouting dst-address-type=!local in-interface=bridge1 per-connection-classifier=both-addresses-and-ports:4/1 action=mark-connection new-connection-mark=WAN3_conn passthrough=yes
add chain=prerouting dst-address-type=!local in-interface=bridge1 per-connection-classifier=both-addresses-and-ports:4/2 action=mark-connection new-connection-mark=WAN4_conn passthrough=yes 
add chain=prerouting dst-address-type=!local in-interface=bridge1 per-connection-classifier=both-addresses-and-ports:4/3 action=mark-connection new-connection-mark=WAN5_conn passthrough=yes

add chain=prerouting connection-mark=WAN2_conn in-interface=bridge1 action=mark-routing new-routing-mark=to_WAN2
add chain=prerouting connection-mark=WAN3_conn in-interface=bridge1 action=mark-routing new-routing-mark=to_WAN3
add chain=prerouting connection-mark=WAN4_conn in-interface=bridge1 action=mark-routing new-routing-mark=to_WAN4
add chain=prerouting connection-mark=WAN5_conn in-interface=bridge1 action=mark-routing new-routing-mark=to_WAN5

/ip route
add dst-address=0.0.0.0/0 gateway=192.168.2.1 routing-mark=to_WAN2 check-gateway=ping
add dst-address=0.0.0.0/0 gateway=192.168.3.1 routing-mark=to_WAN3 check-gateway=ping
add dst-address=0.0.0.0/0 gateway=192.168.4.1 routing-mark=to_WAN4 check-gateway=ping
add dst-address=0.0.0.0/0 gateway=192.168.5.1 routing-mark=to_WAN5 check-gateway=ping

add dst-address=0.0.0.0/0 gateway=192.168.2.1 distance=1 check-gateway=ping
add dst-address=0.0.0.0/0 gateway=192.168.3.1 distance=2 check-gateway=ping
add dst-address=0.0.0.0/0 gateway=192.168.4.1 distance=2 check-gateway=ping
add dst-address=0.0.0.0/0 gateway=192.168.5.1 distance=2 check-gateway=ping

/ip firewall nat
add chain=srcnat out-interface=WAN2 action=masquerade
add chain=srcnat out-interface=WAN3 action=masquerade
add chain=srcnat out-interface=WAN4 action=masquerade
add chain=srcnat out-interface=WAN5 action=masquerade  

注意:路由器有5个物理端口(WAN1、WAN2、WAN3、WAN4、WAN5)和1个无线端口。WAN1和无线端口通过Bridge1连接在一起，连接到Bridge1 (WAN1或Wireless)的网络中的所有节点，现在互联网连接没有问题，而且工作正常。但是当这个网络中的一个节点想要访问一个网站(例如: google.com)时，请求将从所有的互联网线路发送到google.com！因此，对于每个节点，我们将发送2多个请求到一个网站！

我想在网络节点之间划分这些互联网线路，例如，每一种IP都使用特定的internet线，如下所示：

192.168.1.1 - 192.168.1.64: Use first Internet line 
192.168.1.65 - 192.168.1.128: Use second Internet line 
192.168.1.129 - 192.168.1.254: Use third Internet line   

有可能吗？你能帮帮我吗?

Answer 1

您正在尝试使用PCC (每个连接分类器)，但您要求的是基于源IP地址范围的负载平衡。

从配置中删除以下规则：

add chain=prerouting dst-address-type=!local in-interface=bridge1 per-connection-classifier=both-addresses-and-ports:4/0 action=mark-connection new-connection-mark=WAN2_conn passthrough=yes 
add chain=prerouting dst-address-type=!local in-interface=bridge1 per-connection-classifier=both-addresses-and-ports:4/1 action=mark-connection new-connection-mark=WAN3_conn passthrough=yes
add chain=prerouting dst-address-type=!local in-interface=bridge1 per-connection-classifier=both-addresses-and-ports:4/2 action=mark-connection new-connection-mark=WAN4_conn passthrough=yes 
add chain=prerouting dst-address-type=!local in-interface=bridge1 per-connection-classifier=both-addresses-and-ports:4/3 action=mark-connection new-connection-mark=WAN5_conn passthrough=yes

add chain=prerouting connection-mark=WAN2_conn in-interface=bridge1 action=mark-routing new-routing-mark=to_WAN2
add chain=prerouting connection-mark=WAN3_conn in-interface=bridge1 action=mark-routing new-routing-mark=to_WAN3
add chain=prerouting connection-mark=WAN4_conn in-interface=bridge1 action=mark-routing new-routing-mark=to_WAN4
add chain=prerouting connection-mark=WAN5_conn in-interface=bridge1 action=mark-routing new-routing-mark=to_WAN5

并增加以下内容：

add chain=prerouting src-address=192.168.1.0/26 in-interface=bridge1 dst-address=!192.168.1.0/24 action=mark-routing disabled=no new-routing-mark=to_WAN2 passthrough=no 
add chain=prerouting src-address=192.168.1.64/26 in-interface=bridge1 dst-address=!192.168.1.0/24 action=mark-routing disabled=no new-routing-mark=to_WAN3 passthrough=no 
add chain=prerouting src-address=192.168.1.128/25 in-interface=bridge1 dst-address=!192.168.1.0/24 action=mark-routing disabled=no new-routing-mark=to_WAN4 passthrough=no 

不需要标记连接，然后再进行路由标记。您可以根据源地址范围直接路由标记。
