Hello all,

First of all, merry Christmas and thank you for your awesome work on OPNsense.

Since 2.7.10 (2.7.9 was fine), I am observing a quite strange issue. My setup includes a Captive Portal running on my WireGuard interface and as soon as I enable it, my internet connection is getting slower (after roughly an hour it goes down to 600 Mbit/s from 1 Gbit/s (download)). However, I don't see anything suspicious in the logs.

The authentication of the Captive Portal is "Local + Timebased One Time Password" and I have already recreated the Captive Portal from scratch but the issue keeps showing up.

Could this be related to: https://forum.opnsense.org/index.php?topic=50177.0 ?


Please let me know if you need any further logs or information.

Thank you and best,
 a happy OPNsense user

Hi,

It could be related to .10 but not the ticket.  Unsure how to debug this, but you can use

# opnsense-revert -r 25.7.9 opnsense

and a reboot to confirm that is the actual issue or not.


Cheers,
Franco
