@rloeb you said it yourself:
"I haven't the faintest idea what I'm doing"

Uh, ok. You've got a handful of some of the most experienced pfSense users chiming in on this thread trying to help you. From what I've seen, you've spent most of the time complaining about the "horrible interface", how "the device is on another floor and I'm slammed this morning" and generally how much time you've lost or don't have.

Maybe consider taking the time to read and try the suggestions being offered, or at least provide some better debug logs etc so people can try to help you.

Not trying to be rude or dismissive but honestly if you don't have the time or experience (or at least willingness to learn) you really ought to hand off the responsibility to someone who does.

I'm wondering if the latest Firefox has a problem

I am using latest 155.0 of firefox - not having any issues with either the normal php gui or the nexus gui.

I got tired of fighting and reloaded the entire setup from a backup. Interestingly, the backup was from an earlier version, but when I logged in, I found the latest version. Not sure what that's about, but pfsense is operating as needed and I've got a business to run.

Rog

I'll see if I can replicate what happened because it sounds like an edge case we should handle.

If you have console access you can probably just roll back the config to before you enabled nexus. The console menu has an option for that.

It's a small company, and I'm the owner. Once upon a time, decades ago, I wrote a zillion lines of code. Somewhere along the line, I became an "executive." Then I became a business owner... My tech skills have seriously degraded, but they're the only tech skills we have, so I manage the firewall, along with everything else. Unfortunately, my focus isn't on tech details, and Linux was never within my comfort zone. I'm playing with fire here. Or maybe just playing with a firewall...and I haven't the faintest idea what I'm doing.

@rloeb you have to run sh first.

Being one who hates having to start the interpreter before running the command:

sh -c 'for x in webgui/protocol webgui/port pfnet-controller/http_port pfnet-controller/https_port; do val=`read_xml_tag.sh string "system/${x}"`; echo "${x}: ${val}"; done'

What is pfnet-controller???

this is what runs the new gui.

Looks like your old gui is running on the same 8080 port that the new gui http redirect runs on - since you have no ports listed I assume they are just the default for the new gui 8080 redirect and https 8443.

I would suggest you edit these ports in the new gui. You can change both the old php gui, and the new gui ports.

I would take it from that output that you changed your http old gui to 8080, never enabled https. And now your new gui default redirect is stepping on your old gui http port. Correct them to how you want them in the new gui so they do not step on each other.

What is pfnet-controller???

When I connect on :8080, it switches immediately to :8443 and I can login with my previous credentials. But...I desperately need to get to the old interface to make some rule changes to keep the business functioning,

As to get to backup/restore in the new gui

I wouldn't say this

@rloeb said in How to return to "old" interface?:

Horrible interface!

Its a bit rough around the edges, and needs a bit of polish - but sofar it seems have the important bits.. Remember this is designed to manage multiple pfsenses.. Why the front page doesn't have the menus your familiar with.

It is night and day faster than the old gui that is for sure.
