Hello,
Indeed, it seems that there is a visual issue with status of the interfaces when load-balancing is enabled. Apparently, this is not just on RUTX12. It can happen even when the wired WAN is used. However, this is just visual. While testing, the Wired WAN shows as Online, and mob1s1a1 as standby, but the connections are balanced over both interfaces. So there should be no issues with the load-balancing itself. The issue is strictly visual.
This has been reported to the RnD team and they will address this in the future firmware releases.
Thank you for noticing, and apologies for any inconvinience that this may have caused.
Kind Regards,
