RB3011 Speed drops / Packet loss after enabling "Use IP Firewall for Bridge"

RouterOS General
1

I configured 2 RB3011s over the past 2 days for completely different purposes. One of them I was using for receiving a static route, the other I was using as a NAT router with DUAL WAN for a bunch of Wi-Fi access points, and some wired clients.

In both, I had a need to create bridges in order to create separate broadcast domains. In order to use the simple queue feature on one of the routers, I enabled the option “Use IP Firewall for Bridge” on one of the bridges that I had created.

I similarly enabled the option for a different reason on the other router. Both of these two routers were connected to Gigabit WAN networks, but after I enabled this option, I can only pull about 20 meg x 4 meg… and I occasionally encountered packet loss.

As soon as I turned this option off, I was right back at nearly a Gigabit.

Does anybody know why this would occur and / or if there is some better way to accomplish what i am trying to do? I did not have any active firewall rules for either of these routers.

Thanks,

Hi,

How high is the cpu usage running at?

cpu % = 1~5%

Enabling “Use IP Firewall for Bridge” disables FastPath on the bridge. That might explain the problem.
