Mikrotik MULTI WAN Load Balancing *help needed*

RouterOS Scripting
1

hello everyone.
i’m not that good with mikrotik so i have a simple question for someone, and a not simple question for someone like me :smiley:
if anyone can find the time to respond, here is my question

i have 4 internet connections from 2 diferent ISP
2 x 1 cable modem connection 4 Mbps/1Mbps
2 x 1 adsl connection “ppoe” 8 Mbps/768 kbps

i have “RB750G” 5 port.

WAN1- 192.168.1.2 > 4 Mbps/1Mbps “already conected "
WAN2 - 192.168.2.2 > 4 Mbps/1Mbps “already conected”
WAN3 - 192.168.3.2 > 8 Mbps/768 kbps " PPPoE Client” bridge mode
WAN4 - 192.168.4.2 > 8 Mbps/768 kbps " PPPoE Client" bridge mode
LOCAL - 192.168.0.1 LAN


conected clients will be from 30 to max 40 , loadbalancing + failover

can you tell me if this is possible , and if yes. always if you find the time to tell me how.

Thanks.

Change the IP@ to your plan and it should work fine.

PCC is not very good with un equal links.

1st of all you will not have a 100% load balancing with different ratio of links …

try to send traffic twice to WAN3 & WAN4
where:
WAN1 per-connection-classifier=both-addresses-and-ports:6/0
WAN2 per-connection-classifier=both-addresses-and-ports:6/1
WAN3 per-connection-classifier=both-addresses-and-ports:6/2
WAN4 per-connection-classifier=both-addresses-and-ports:6/3
WAN3 per-connection-classifier=both-addresses-and-ports:6/4
WAN4 per-connection-classifier=both-addresses-and-ports:6/5

but as you say your up are different in the 2 links and it is lower in WAN3 & WAN4 …
so if you have a high traffic in up way then i think you will see a bottleneck in the up stream in WAN3 & WAN4 …

send traffic twice to WAN3 & WAN4 , will try this :wink:
