Updated - first impressions

[Patrick M. Hausen]

Same here. I submitted the crash report. But this does not look like the known Nut segmentation fault but rather like a UI/Frontend problem.

Thanks Patrick. I created an bug report: https://github.com/opnsense/core/issues/10534

[muchacha_grande]

The upgrade went fine here without problems... almost everything is working as expected.
One comment(1) and one caveat(2):
1. I'm with Patrick about the services widget. A proper header will not occupy much space and will make it more in line with the other widgets.
2. Accessing Nginx->Configuration page is crashing.

EDIT: this looks like the exact same problem with the nut configuration page reported by julsssark

[Patrick M. Hausen]

That's the second one. Services > Nut > Configuration, too. I see a hotfix incoming 😉

[muchacha_grande]

Until a hotfix or 26.7.1 is released, opnsense-patch 14710e7 will fix the crash on Nginx, NUT and Squid menues

I am not sure about this one, so I am posting it here. I think I do see a higher RAM-usage. But I have no historical data and that VM has only 1 Gig of RAM to begin with (UFS).
Right now, after a reboot, it looks okayish. Maybe others have better data.

Proxmox?

@Patrick:
Can you confirm that DestNAT (IPv4) on your side? In my setup it did not work. I try to figure out if i have a config issue that still worked with 26.1.11_10 or if its version related.

[Patrick M. Hausen]

Can you confirm that DestNAT ... does what, now?

[seed]

Sorry.
Can you confirm that DestNAT (IPv4) is working on your side?

[Patrick M. Hausen]

Yes, no problems.

Your OPNsense VM only has 1 GB of RAM ?! How ?!

I have a dedicated Mini PC that happens to have 16 GB RAM because the previous owner bought it like that and my typical RAM useage for OPNsense is :
- Around 750 MB after a fresh reboot.
- Around 2 GB after running for some time and getting to an average operational state so to speak.

It has been like that now all the way up to 26.1.11_6 and I only use :
- Firewall
- NAT
- Routing
- DHCP
- 4 Interfaces :
igc0 - WAN - VLAN sub-interface with DHCP Client active.
igc1 - Default LAN
igc2 - Home Network
igc3 - Dedicated Assign VLANs Interface with for now just a Guest Network.

Total number of IP Addresses going through this is somewhere between 30 to 40 usually IIRC :)
