Quick update:

I tested the hard drive in Bios and seemed working. I reinstalled OPNsense on UFS file system. The disk space problem is gone. I updated then restored my backup. Well, I had my VLANs mixed up. Somehow, the firewall rules and DHCP reservations for VLAN X would show up under VLAN Y. The interface assignment have not changed. I have to re-do it all manually. I am not sure there is a better way to do it but this is my primary home firewall/router. Terrible experience!!

I had to force shutdown my firewall to reboot after I lost connection during a storm. I'm running the firewall baremetal. Anyhow,  the system failed to boot and showed damaged tar files,  attempting repair, lasted forever. So I decided to clean install opnsense and restore from backup. I was able to restore the majority of opnsense config but not the add-ons for they required update to the newest opnsense version. 

TL;DR: The system now show updates are available but it requires 13.9MB more disk space. I have 899MB available. Where is the problem?

1. I restored UFS install up ZFS fresh install
2. I restored before I upgrade the system.
3. Is this a HDD problem. It is an nvme so I don't expect so.

Good luck finding a solution. I have the same exact issue. I tried baremetal install and virtual on proxmox. Same result.

I would like to setup NordVPN a gateway to route certain traffic from few clients on my network. I was able to get the gateway connection up and running. Official instructions dictates routing ALL traffic through VPN which is not what I want to do. I tried tagging packets and sending them over to the VPn gateway but devices did not receive an IP. Any suggestions how to approach this?

Dear all,
I am facing some overheating issues with my topton N5105 opnsense box. I would like to migrate to VM (proxmox) on another machine that has more power and actively cooled. How can move settings from one system to another? I tried config backup and restore and did not seem to have made any changes to the new installation VM instance.

I am noob at this. I have my network setup as ISP Arrris modem --> OPNsense router/firewall --> network switch --> APs on MESH. I have my network segregated into VLANs each distributed to their respective Wifi. Recently, I note transient internet connection drop outs intermittently on a particular Wifi/VLAN. I do not have stringent firewalls of any sort at least not on this VLAN. The problem happened simultaneously on two devices connected to the same troublesome Wifi, so I do not think this is a peripheral device issue. I am not sure how to troubleshoot this at the level of opnsense or switch. I appreciate some guidance.   

Restarting the machine will do  ;)

I have a TOPTON device with 4 ports. I followed this guide https://docs.opnsense.org/manual/how-tos/lan_bridge.html to create a bridge interface close to the attached diagram. I noticed that I have errors out on the bridge interface and VLAN10. The physical interfaces OPT3 and OPT4 are enabled but unused at present. I tried to disable unused interfaces and it did not solve the issue. I attached a diagram for the interfaces and screenshot from my OPNSense instance. Shall I worry about these errors at all?

Thanks.

Thank you so much. Very nice drawing  ;D

Do you want these ports to be port based VLAN members, i.e. carrying untagged frames?

What you need to do in this case is create your VLAN on the trunk port (you already did that), then create a bridge interface with that VLAN and the untagged additional port as members. Then, and this is important, assign the logical interface (Interfaces > Assignments) including IP address configuration etc. to the bridge interface, not the VLAN interface. Don't assign anything to the VLAN interface at all.

Additionally you might want to change two kernel tunables as documented in the "LAN bridge" chapter of the wiki.

HTH,

This is exactly what I intended to do; that is to bridge logical to physical interfaces. The question is now the trunk port does not have that VLAN anymore, right?

I am setting up a Topton 4-NIC box. I assigned defaults of one NIC for WAN and another for LAN. I have 2 unassigned ports (OPT2,OPT3). My LAN is a trunk port and has multiple VLANs. How can assign one of those VLANs to unused OPT interfaces? The reason I want this because my desktop has 2.5gb NIC to utilize the speed on my network. I have TL-SG3428X gigabit switch. My NAS is connected to SFP+ port. I plan to connect my LAN trunk to another SFP+ port on the switch, and utilize one of the OPT ports on OPNsense box for my desktop.

I recognize that I cannot create VLANs on bridged interfaces. Can create a bridge assigned to VLAN? (thinking loud here).

Thank you so much.

I have an N5105 mini machine that I intend to use with OPNSense without a hypervisor. I would like to set up another OPNSense instance on Proxmox as a backup HA. Is this doable? I learned from forums that interfaces has to have similar names for HA to work.

I currently have Arris S33 modem connected to a virtualized opnsense instance. My LAN is connected to a managed L2+ smart switch that carries out my VLANs. I initially thought to set up two virtualized instances but I dont have a physical router to hand over IP addresses to downstream opnsense instances. I do not plan to use my L2+ smart switch to handle DHCP.

I am open to suggestions.  Thank you.

I uninstalled Zenarmor (Sensei) for I found Elasticsearch Database was taking so much disc space. And the surprise, all interface errors disappeared. It has been 24 hours so far. You may close this post. Thank you.

I have OPNsense running on Proxmox. This VM has an assigned 80 gb storage setting on 250gb SSD. I suddenly had my drive full that the VM is no longer able to run. so I moved out some VMs to empty some space but this VM appears to consume over 200gb by itself on the proxmox side, but only 36% full on the VM side. I ran fsck -fy  / with output marking disk as "dirty". OPNsense self check marked file system fine. I can see on df -h one drive is consuming as such (see pic). tunfs TRIM is set to disable. I am unable to enable this because the disk is marked as dirty. Of note, VM is running on ext4 file system (not ZFS) and I have enabled the Discard option in HDD configuration on Proxmox side.

Appreciate help to approach this issue.

I have similar issues to this date which appear to happen on truncated VLAN ports only. It seems to come up often. See previous posts if that helps.
