I have both a Balance One Core and a Balance 20. I have upgraded both to firmware 8.0. Prior to and after the upgrade, the Balance 20 works with Web Admin Port set to 8080.
Prior to and also after upgrade, the Balance One Core will let me set the Web Admin Port from 443 to 8080, save, and apply. I can then successfully login from the LAN side using 8080. A few minutes later, the Web Admin Port magically stops working on 8080, so I log in on 443, and sure enough on the System page, the Web Admin Port has reset itself from 8080 back to 443. I have tried resetting it from In Control 2 and also locally by directly logging from the LAN side. No success and the port is constantly resetting to 443.
Please let me know if this is a know bug for the Balance One Core running 7.1.2 (my pre-upgrade version) and 8.0.0 since this problem exists on both firmware versions.
