HI I want to enhance my home server infrastructure with an advance firewall solution based on opnsense, pfsense or ipfire in a virtualized enviorment based on proxmox. As this would allow my do this in a power and cost effiecent way, while still allow me to utilizing the 10G connection from my...

Hello everyone, This is a question about possibilities, because I cannot seem to find anything like this when searching. This may be more of a Hetzner issue but it looks like folks on here are pretty well versed in Hetzner so I am hoping someone has some ideas. The premise: I am attempteng...

Hallo allerseits, ich betreibe Proxmox auf einem Mini-PC und OPNsense auf einem weiteren. Beide sind über einen Zyxel managed Switch miteinander verbunden. Es gibt ein Management VLAN5 und 2 weitere (VLAN10 und VLAN20). Auf Proxmox sind 4 VMs konfiguriert. Jeweils 2 in einem der beiden VLANs...

Not sure if this is the right place to post this... moderator do let me know if this is not appropriate. I have ordered a CPU N100, 16GB DDR5 Ram, 118GB P1600X Intel Optane SSD, 4 Ports Intel i226. Currently I also have a 3 Nodes Clusters. With only 2 Nodes running at a time, 1 running my...

Hi, posting to ask for help. I've been reading a bunch of different posts and trying different configurations without any success. I'm trying to setup my proxmox node to run OpnSense as a VM and use it as router and firewall. The main problem is that the WAN does not assign an IP from my modem...

Hello, we try to build a PVE Cluster with a EVPN VXLAN SDN. The configuration for the VM to VM Communication is working, also SNAT with the Subnet Gateway is working. Now we try to replace the subnet gateway with an external OPNsense, so that the OPNsense can provide all required network...

This how-to-fix post to inform people on how Suricata crashes with OPNSense on Proxmox (any version) can be remediated. The advisories here may not be suitable for production environments, I trust you know this already. Context VM-hardware has Q35 chipset and uses virtio network interfaces...

Hello. I'm having a bit of trouble getting an opnsense virtual machine to respect settings for TX and RX slots of my network interfaces as set in the host. I have optimized my network configuration for opnsense by following many of the recommendations on this forum and other Internet sources...

Hallo, ich bin neu hier und allgemein in der Linux und Proxmox - Welt, aber auch allgemein in der IT. Es fehlt mir sowohl an Netzwerk Kenntnissen, als auch Proxmox. Dennoch würde ich gerne meine Konfiguration zu zeigen und nach einem Rat fragen. Mein Setup ist ein PC mit nur einem physischen...

Hi, i currently have some issues with ipv6. My plan is to create a setup like this: "proxmox <-> opnsense <-> vms". I'v allready successfully setup ipv4 with nat and all stuff, which works fine, but i would also like to use ipv6. With my current setup i can reach opnsense with it's ipv6 from...

I'm switching over from an Omada router to OPNsense. I have it installed as a virtual machine with Proxmox. LAN seems to be working fine, but I can't get a WAN IP address. I don't believe that my ISP requires that I provide them with the new mac address because I've switched routers in the past...

We have quite a few installation running OPNsense on Proxmox and they all run fine. Since a couple of months we also have one instance on a Hetzner root-server (EX101, Intel Core i9-13900) that causes me a lot of headaches and I still cannot figure out the cause for these issues: - getting the...

Hi all, having some problems which I hope I can resolve because I *REALLY* want to run Proxmox on this machine and not be stuck with just OPNsense running on bare metal as it's infinitely less useful like this. I have a super simple setup: 10gb port out on my ISP router and PPPoE credentials...

Hello everyone, NOTE: in my message below, I make assumptions and guesses based on my research, but it’s very possible it’s full of mistakes and misunderstandings on my part…o_O To preface: I am pretty new to OPNsense (although I had just a bit of experience with pfSense), and entirely new to...

Hi all, I'm working on my first setup at Hetzner and I can't find any examples of what I am attempting to do. I'm hoping for some insight, an interfaces config or step by step if it's available would both be very helpful! While there's plenty of instructions with regard to hosting OpnSense...

Hi, ich bin Neu hier und habe wahrscheinlich wie schon mehrere Menschen vor mir dasselbe Problem. Ich habe die anderen Posts schon durchgesehen und nichts gefunden was mir geholfen hat. Vorweg bin kein Linux Profi, habe aber Spaß an der Materie. Meine Ausgangssituation gerade: 1x Dedicated...

I figured its always best to start with what are my current goals or ideas that should lead the discussion for specific items. I think my use case is pretty basic (hoping) and look forward to any feedback. It's pretty easy to overshoot the types of equipment or tech needed, and while I don't...

Hi there, I’m using OPNsense as a firewall and VLAN. But I’d like to access (SSH mainly) the VMs at the VLAN from my LAN, but every firewall rule I make on the VLAN seems to block the LAN. Ping or SSH from LAN results in a time-out. What am i doing wrong? Firewall rules VLAN below: Pic1: I’ve...

Hello there! I just started using Proxmox VE 7.4 (6.2) as of last week with a Lenovo ThinkCentre M900 Tiny I got off Amazon Renewed, mainly for the purpose of running it as an OPNSense router and as a host for Home Assistant OS, plus a few Docker containers. So far, I've been able to install...

I want a highly available OPNsense setup in my Proxmox cluster. OPNsense has native HA features, but they require some manual tweaking to set up and I don't want to run a separate OPNsense VM for each node in my cluster. So I had the idea of just setting up two VMs on separate nodes and have...
