New setup DEC 750

[Hedgehog]

Hi,

I'm new to Opnsense. Hopefully someone can help
I have a DEC750 which I purchased about 2 weeks ago.

I had kept the unit disconnected from the internet. I've been reading guides, experimenting with settings, familiarising with the UI and all things new to me.

I'd moved the LAN to a SFP port, created a new admin, changed the password for root then disabled root for the GUI.

And it all worked.

I connected the unit to the internet today, pasted the license key, started an update.
The updates completed and after a reboot I logged back in and then got disconnected shortly after. And I cannot connect to the DEC750 anymore.

My laptop doe not receive an IP address using my normal connection (or on any of the ports on the DEC750).

I thought no worries. Just use the console connection and reset to default.
My new admin login is recognised but I receive a message "This account is currently not available" and I'm logged out.
I then tried root and my new password or the default password are not recognised.

How can I factory reset this unit please?

Thanks in advance.

I couldn't immediately locate a manual but there appears to be a standard pin hole on the front panel (between the console plug and the power LED).

I would try first connecting with the serial cable, boot to single mode choosing option 2, press Enter whan asked about the shell to use, then run these commands:

Code Select Expand


/sbin/mount -u /

/sbin/zfs mount -a

rm -f /conf/config.xml

reboot
These steps would bring you the initial configuration wizard - however anything else you may have installed is still on the disk albeit with no configuration present.

If the above fails - i.e. you have other problems - then get the 24.10 ISO and image it to a stick, then do a fresh install.

Thank you. I believe the pinhole serves as an on/off function. Not like a reset on other devices.

Re-install is the easiest method for a complete factory reset, IMHO.

This was amazing! Thanks! It worked. I'm back to the beginning.

It's so frustrating. I do not know what I had done wrong. I'd been reading, going slow, I had made some basic changes and then after going online and updating.... Blammo

So, I had given up and was trying to do a fresh install from USB and encountering other problems. None of install the guides really cover everything.
Like, no matter what I did, I could not see a press any key option to start the configuration importer message. I had to press esc and choose boot manager to get it to boot from the usb. After logging in as installer and choosing a zfs install, I was receiving a not enough disks for zpool message after selecting stripe.

I searched zpool in the forums here and 8 pages of threads. The contents of which made me realise how little I know.

And then I thought to check to see if I had a reply to my post.
Thank you very much. I will save your advice.

I can log back in on default ports and password.
And the version is
OPNsense 24.10.2_6-amd64
FreeBSD 14.1-RELEASE-p7
OpenSSL 3.0.15
And the license registration appears to have stuck as it shows an expiry date in Mar 2026
And system>firmware>status shows the update on 4th April.

Are updates often so dramatic?

I noticed in System>Firmware>Changelog that I am seeing versions and dates going back to 20.1 2020-01-30
Do you know if these are actually install dates of previous versions?
Is my brand new DEC750 actually 5 years old?

You first need to start the setup from USB.
At some point, you get the choice of using the importer.
Then the choice to do manual or automatic interface configuration.
That gets you to a live environment. OpnSense is running but nothing is persisted to disk just yet.
Logging in as installer starts the process of persisting the live environment to disk.
That's when you are asked about UFS/ZFS, which disk to use.

Wrt System > Firmware > Changelog, it appears to contain all historical versions of OPN, with the current one highlighted.
It is not a history of installed firmware versions.

Thanks for the tips and good to know about the change log. Thank you
