Bug Report: Firmware 4.4.3.710328 — DHCP option 42 solicited but ignored

Product: QSW-M3216R-8S8T
Firmware updated to: 4.4.3.710328 (20260526)
Previous firmware: 4.3.x (prior version)

Steps to reproduce:

in dnsmasq, configure option 42 - dhcp-option-force=42,192.168.1.1
Reboot switch
qnap switch solicits option 42, but ignores it in the dhcp response. it accepts all other options.

Hi Dan and welcome to the forum.

All bug reports should be made directly to QNAP by creating a support ticket: QNAP Account Center

Dan812 · June 15, 2026, 12:35am

your bug report portal is bugged. it doesn’t let me select firmware 4.4.3.710328

Dan812 · June 15, 2026, 12:41am

it won’t let me create a ticket. it just says “validate fail” with no explanation why.

OneCD · June 15, 2026, 12:42am

Not mine, but choose the nearest firmware version after yours, and report that too.

Dan812 · June 15, 2026, 12:43am

i’d love to create a ticket but the portal won’t let me. it would be nice if it actually gave a reason why “validate fail”.

OneCD · June 15, 2026, 12:44am

It might be trying to confirm your device serial number. Try adding it as a ‘My Device’ item, then create the support ticket.

Dan812 · June 15, 2026, 12:49am

nope. still “validate fail”.

OneCD · June 15, 2026, 12:51am

No worries. Try creating a support ticket with “my device does not have a serial number” selected.

Dan812 · June 15, 2026, 1:30am

exact same error. “validate fail”.

i think we can assume at this point it has nothing to do with the serial number.

OneCD · June 15, 2026, 1:37am

Are you attempting to attach any files? If so, don’t do this. Create the ticket first.

Dan812 · June 15, 2026, 2:18am

no, i’m not attaching any files.

OneCD · June 15, 2026, 2:22am

Have you tried another web browser?

@SteveKo is there anything QNAP can do to help @Dan812 create a support ticket? I’m out of ideas.

CY1 · June 15, 2026, 3:08am

Hi @Dan812 , thanks for your information. We will check it and reply to you later.

SteveKo · June 15, 2026, 6:01am

Hi @OneCD

We’ll also check whether there are any issues with the support ticket page. Thanks for the report!

SteveKo · June 16, 2026, 9:47am

Hi @Dan812

Would you mind opening a support ticket again? We need further information to assist you with this. If the ‘validate fail’ error still appears, please let us know, and we will continue to help you resolve it. Thanks!

Dan812 · June 17, 2026, 2:05am

The firmware version selection list is still very old and does not let me select the current version.

But the validate fail seems fixed now.

SteveKo · June 17, 2026, 9:48am

Glad to hear you were able to open the ticket successfully! Our Support Team will follow up with you through the ticket. Regarding the firmware list, I suspect it may be related to the product line — I’ll pass this on to our internal team. Thanks for the suggestion!
