promiscuous mode enabled ? Is this affecting NAS local streaming speed ?

[numbertwo]

I'm not sure when did it happened, but i found out today that the streaming speed from my NAS to my home media is lagging and almost choking.

I did the upgrade to TrueNAS-12.0-U3.1 five days ago. So i went into the Truenas admin console, i noticed that there is this 'promiscuous mode enabled', i don't remember seeing this in the previous releases, does this has any effect to my sudden network speed drops?

i only has got one jail running qBittorent, it has both VNET & Berkeley Packet Filter ticked.

HDD statuses in the Dashboard show OK with 0 disk write error.

Anyone has a clue ? Thanks in advance.

Dis you find a fix for this? My Plex Jail only uses 10% of bandwidth :s

You're using a realtek NIC... that's likely to be the source of the issues... promiscuous mode is not.

All promiscuous mode means is that the NIC will listen to traffic for more than one MAC address (required for jails to work).

Realtek or not

• disable autostart for all jails
• reboot
• create an interface of type bridge named bridge0
• set the physical interface as the member
• in the physical interface check the box "Disable Hardware Offloading" - this is mandatory!
• in the physical interface remove the IP configuration - no static address, no DHCP, nothing
• put IP configuration on bridge0 instead
• test and save
• reboot for good measure
• re-enable jails

I tried to follow your instructions @Patrick M. Hausen for troubleshooting a different issue, and when trying to create the bridge in the gui I'm only seeing one field for ip address; when left blank and I hit "apply" the mandatory checkbox says "Offloading capabilities is not supported for bridge interfaces." Am I doing something wrong?

You need to check the "Disable Hardware Offloading" box in the physical interface settings, not in the bridge interface settings. Also if the physical interface has got an IP address configured, don't forget to remove that and put it on the bridge interface instead.
