Mikrotik DUAL WAN Load Balancing using PCC method. Complete Script ! by zaiB
Following is a complete script for Mikrotik to combine/load balance two DSL lines. In this example I used MikrotikT RB750 5 ports router.
2 ports were connected with two difference DSL Routers,
and 3rd port was connected with User LAN.
Both DSL are of same speed , i.e 10Mb each.
DSL MODEM IP’S
DSL MODEM 1 = 192.168.1.1
DSL MODEM 2 = 192.168.2.1
Also don’t forget to rename the interface names accordingly.
In my personnel experience , If users request are directly hitting Mikrotik configured with PCC , then you will get good load balancing. Use src-address as classifier, this way you will get rid of problems like https/broken link, streaming issues etc. Load balancing using this PCC technique (src-address) will be effective and balanced approach when more and more connections (from clients) that occurred. I also recommend to use SQUID proxy server along with mikrotik , either parallel or in front or backend , for better response time and it will also increase good browsing experience to users.
If somehow you are not satisfied with the src-address approach,play with the PCC-Classifier, then Try both addresses and ports as the classifier. While this will randomize things the most and in theory give you the most fair allocation of bandwidth, BUT there is also a good chance that it will break certain things like banking web sites and some forums. This is because often times a HTTP requests will generate several connections, so there is a chance that some requests may go out a different route than the initial one, and that will break secure web sites. For that reason I usually stick with src-address for PCC load balancing.

All Done ! Now Test the link by putting user load, the more multiple users load you put on it, the better Load Balance result you will get

I have 2 PTCL Broadband each 4MB merged with Mikrotik 3.20 configured as Hotspot and PCC Loadbalancing.
ReplyDeleteThe problem is sometimes 1st or 2nd WAN atomically get restarted and all the hotspot active users complain about disconnection their internet disconnection for at least 10 seconds.
Can you help me that all the active users dont get this problem even a single WAN is stable.
I really need your help asap.
Waiting for reply if any detail required to solve my issue.
Hi can I have your number so I can talk to you on if you're willing to help me?
ReplyDeleteAfter configure the MiKroTik with the help of above configuration. I faced problem which is follows.
ReplyDeleteWhen either WAN1 or WAN2 goes to down, then its working from WAN2 or WAN1. and when WAN1 or WAN2 UP again then both links are not working parallel without reboot the mikrotik.
Please help me

i have some problem in my mikrotik router single wan1 is working but if i stop the wan1 than wan2 work
ReplyDeletei won't to work both someone help me please
