Version 23.09 GUI Crash after changing WAN from DHCP to PPPoE

[Yves 1]

Hello all,

I have a pfsense running on a Netgate SG 1100. Brand new.
I had it configure with the WAN interface configured as DHCP. It worked fine.

Now, I am trying to configure the WAN interface to PPPoE.
So I changed it (and also disabled) the IPv6 configuration (not used).

When, using the Gui, I click on 'Interfaces - Wan' it redirects me to 'https://192.168.1.1/interfaces.php?if=wan' (which I think is correct)... but it displays (in the browser):

Fatal error: Uncaught TypeError: Illegal offset type in /usr/local/www/interfaces.php:1996 Stack trace: #0 {main} thrown in /usr/local/www/interfaces.php on line 1996 PHP ERROR: Type: 1, File: /usr/local/www/interfaces.php, Line: 1996, Message: Uncaught TypeError: Illegal offset type in /usr/local/www/interfaces.php:1996 Stack trace: #0 {main} thrown

Ouch !

On the dashboard page, I see : Netgate pfSense Plus has detected a crash report or programming bug. Click here for more information.
and when I click that, I get the following:

So , I am a bit stuck there :-(

On the console, the interfaces look ok...

Please also notice that the WAN interface is physically NOT connected !

The sad part is ... I can't reset the interface to DHCP any more :-(

Any brilliant ideas from someone ?

Thank you in advance,

Yves.

@Yves-1 said in Version 23.09 GUI Crash after changing WAN from DHCP to PPPoE:

/usr/local/www/interfaces.php:1996

That's this: https://redmine.pfsense.org/issues/14949

It's fixed in dev snapshots and available in the recommended patches list in the System Patches package.

Hello Steve,

Thank you so much for the efficient and prompt reply..
However.. I can not search (and install) the system patches.. since the WAN interface is down :-(

How I can proceed ?

Yves.

You can bypass that bug by setting up the PPPoE config first in Interfaces > Assignments > PPPs.

Then select that as the WAN.
