Multi WAN (3+) PCC load-balance problems

Mon Jun 23, 2014 6:56 pm

Hi, I'm trying to setup my multi wan load balance with x86 system (tried with RB750 too but low bandwith). Configuration goes OK but my problem is that only 2 connections are working at the same time, or one it depends, but never more. I have 4x15MBit/s but for now I'm just testing with 3 of them. Providers on all of them are the same. Basicly WAN2 & 3 works and WAN1 doesn't. Or just WAN1 works. When i disable #3 first 2 works and when all 3 are enabled sometimes just first works, sometimes, 1 and 2 but mainly 2 and 3. And bandwith is around 30MBit/s sometimes a little more but never 45+. To make story short, heres my config so that you can sugest what am I doing wrong...
Code: Select all
/interface ethernet

After upgrading 6.15 I face the same problem. İt changes but always one of the wan interface stops traffic and waits. I will downgrade 6.10 and try again... did you try that?

Backup your router
delete all mangle rules
import the above

let me know.... it might work!
Code: Select all
/ip firewall mangle

With this config only 1 works (if all enabled first one only works...), with my config I could at least mix 2 connections but not 3 and with this theres no balancing at all, just failover...
