General Discussion / Internet connection drops on certain VLAN

« on: October 13, 2022, 04:10:43 pm »

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.

General Discussion / Bridge network - Errors out

« on: October 04, 2022, 05:36:10 am »

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.

General Discussion / VLANs on multiple interfaces

« on: August 29, 2022, 01:44:04 am »

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.

High availability / HA requirements

« on: August 13, 2022, 03:07:21 am »

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.

General Discussion / OPNsense disk is full

« on: June 21, 2022, 11:38:19 pm »

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.

General Discussion / Errors Out on VLANs

« on: May 20, 2022, 07:33:46 pm »

I setup OPNSENSE virtualized on proxmox desktop machine.  I use Intel I350 Quad Port by CISCO UCSC-PCIE-IRJ45 via bridge in proxmox. I have 1 port for WAN and 1 port for LAN (and carries all VLAN segments). I use managed switch by TPLink TL-SG108E between LAN and my Wifi AP. I exclusively use VLANs on my network and preserved LAN for management. I have over 1300 errors outs on firewall statistics.

How can I approach this issue? Thanks in advance.
