I have the following issues on port 11 and 12:
I´ve bridged both ports with a software bridge (hardware bypass mode is off).
I enabled the "Use IP Firewall" feature on the bridge, added a few mangle rules and a queue tree.
Immediately after enabling the queue the ports go on/off every few seconds - dropping my connections and make them practically unusable. If i move the same configuration to other ports (lets say port 6/7), everything works as expected.
If i disable the queue tree, everything works on those ports; So it definitely happens only on those 2 ports and only if queue is enabled.
I have everything running (including queue and complex rules) on port 6/7 - whithout any issues.
I have no idea why that issue show on those ports only. Anybody knows?
Edit: It may be helpful to add, that i already disabled auto-neg and full-duplex without any result.
