Hi guys. I have searched google for my issue but it seem hard to find out I'm using 8 wan 60Mbps with PCC load balancing for a dormitory.
After settup loadblacing I used speedtest to test my speed and it worked well, but the problem happened with gaming, the ping is so high and sometime the connection is lost. So i wonder what is the best load blancing approach for my situtuation.I would appreciate if someone had any opinion about it.
Here is my scrip:

Chances are it's too random, you have the PCC classifier set to both-addresses-and-ports. Try setting it to both-addresses to keep multiple connections to the same IP from the same host on the same link, or try moving it to src-address so that a given host will always use one WAN.

This will help with HTTPS sites and forums as well, since for security reasons they do not link to see connections coming from multiple public IP addresses.

You can try with this script to solve your problem , but it just with two lines ,you can extend it with eight lines.

Best solution would be to have QoS implemented, prioritising low latency traffic. BUT I'm not sure if QoS and policy based routing are compatible, as BOTH use connection-marking to do its stuff.

Anyone combined QoS & policy based routing?
