mikrotik load balancing 5

When we want to make Loadbalancing system used Mikrotik 2.9.x, we can using the rule from here. But there is little different with Mikrotik 3.x Ok then, let's started, i will use 5 connection here.

IP Address and Mangle

The router has 5 upstream (WAN) interfaces with the addresses of 10.111.0.2/30; 10.112.0.2/24; 10.113.0.2/30; 10.114.0.2/24 and 10.115.0.2/30. The LAN interface has the name "Local" and IP address of 192.168.0.1/24.

For the ip firewall mangle, 5 uplink connection need 5 connection mark and 5 routing mark.Mangle 1 : nth : 5,1

Mangle 2 : nth : 4,1Mangle 3 : nth : 3,1Mangle 4 : nth : 2,1Mangle 5 : No nthHere the explanation :Mangle 1 : read all traffic and match 1/5 of trafficMangle 2 : read 4/5 traffic and match 1/4 of they traffic (1/5 total traffic)Mangle 3 : read 3/4 from 4/5 traffic above (or 3/5 total traffic) and match 1/2 traffic above (1/5 total traffic)Mangle 4 : read 2/3 from 3/5 total traffic (or 2/5 total traffic) and match 1/2 traffic above (1/5 total traffic) Mengle 5 : read the rest of traffic (1/5 total traffic)

Thats it. Now you can try your setting.

Explanation First we give a code snippet and then explain what it actually does.

Mangle :


broadcast=192.168.0.255 \

interface=Local comment="" disabled=no


broadcast=10.111.0.255 \



broadcast=10.112.0.255 \


The router has two upstream (WAN) interfaces with the addresses of 10.111.0.2/24 and 10.112.0.2/24. The LAN interface has the name "Local" and IP address of 192.168.0.1/24.

/ip firewall mangle add chain=prerouting in-interface=Local

connection-state=new nth=1,1,0 \

action=mark-connection new-connection-mark=odd


First we take every second packet that establishes new session (note connection-state=new), and mark it with connection mark "odd". Consequently all successive packets belonging to the same session will carry the connection mark "odd". Note that we are passing these packets to the second rule (passthrough=yes) to place a routing mark on these packets in addition to the connection mark.

add chain=prerouting in-interface=Local connection-mark=odd


new-routing-mark=odd passthrough=no comment="" disabled=no

The rule above places the routing mark "odd" on all packets that belong to the "odd"

connection and stops processing all other mangle in prerouting chain rules for these packets.

add chain=prerouting in-interface=Local connection-state=new

nth=1,1,1 \

action=mark-connection new-connection-mark=even


add chain=prerouting in-interface=Local connection-mark=even


new-routing-mark=even passthrough=no comment="" disabled=no

These rules do the same for the remaining half of the traffic as the first two rules for the first half of the traffic. The code above effectively means that each new connection initiated through the router from the local network will be marked as either "odd" or "even" with both routing and connection marks.

NAT

/ ip firewall nat add chain=srcnat connection-mark=odd

action=src-nat to-addresses=10.111.0.2 \


add chain=srcnat connection-mark=even action=src-nat to-

addresses=10.112.0.2 \


All traffic marked "odd" is being NATted to source IP address of 10.111.0.2, while traffic marked "even" gets "10.112.0.2" source IP address.

Routing.


scope=255 target-scope=10 \

routing-mark=odd comment="" disabled=no


target-scope=10 \

routing-mark=even comment="" disabled=no


target-scope=10 \

comment="" disabled=no comment="gateway for the router

itself"

For all traffic marked "odd" (consequently having 10.111.0.2 translated source address) we use 10.111.0.1 gateway. In the same manner all traffic marked "even" is routed through the 10.112.0.1 gateway. Finally, we have one additional entry specifying that traffic from the router itself (the traffic without any routing marks) should go to 10.112.0.1 gateway.
