pfSense on Proxmox installation and configuration – Step-by-step



What is better than one open-source tool? How about two?! Proxmox and pfSense are two great open-source tools. The pfSense firewall is a well-known enterprise-grade firewall that has many features and capabilities. Proxmox is a great open-source hypervisor. In this video, we take a look at pfsense on Proxmox installation and configuration and see how we can easily get pfSense installed on Proxmox in the home lab environment.

  1. thx for the video. I was wondering. When you create pfsense as your firewall connecting the internet how will you update the Proxmox hypervisor? If you update it it doesn't have an internet connection anymore because the pfsense VM will go down I guess.

  2. so I have 3 LAN cards in my proxmox, all are connected to the switch, where also cable from the router comes. I understood it is a router (provided by ISP) that deals with IP on the WAN side but here you are saying something different. I am not sure how to connect all these things?
    Should the cable from the router come directly to the LAN card assigned as WAN on pfsense? and the other cards to the switch?
    or both: WAN and LAN cards can be connected to the same switch, where the cable from the route comes?
    can WAN and LAN be in the same segment (192.168.1.x)?

  3. Hello, I just put the new virtualized PFsense online, all good but the connectivity seems to be quite slow. It should be around 500m/s but I'm getting 100, any idea where I should look at?

  4. the only problem that virtualised pfsense that it is still connected to you physical upstream firewall, is there a way to directly connect your isp modem to WAN interface of your pfsense?

  5. Thanks for the great video. I have a few questions regarding this…

    I purchased a very nice mini PC with an Intel Core i7 1165G7 with 6 2.5 Gigabit LAN ports, 64Gb of RAM, a 2Tb Nvme Barracuda plus a 4Tb SSD (I think it is overkill for just pfSense). My idea was to install Proxmox on it and Virtualize pfSense plus, AdGuard, Uptime Kuma and a few other things on it (I currently have 2 AdGuard VMs, Uptime Kuma and some other things in a dual Xeon CPU server but it is somewhat old so This new one is much better. When I started thinking on the installation, I realized that the Proxmox server I have now was installed taking an IP address from the ASUS Router I currently have. That ASUS router works thru the Fiber modem which is in Tunneling mode. Everything else gets their IPs from that Router too.

    So, now I want to replace that router plus proxmox server with this new device to run Proxmox, The router and the other things I have. But how do I get the Proxmox server to get an IP from a router that currently does not exist? I first need proxmox to be able to virtualize pfSense… Can you please gece me some pointers on this?

    Many thanks, I am a big fan of your channel. Your videos are great!

  6. Great content!! Let me ask you, Do you prefer Proxmox or Bare metal installation for a pfsense firewall? if you have vpn and encryption proxmox is giving me performance issues?

  7. I like your presentation it is smooth and easy to follow. Often it is the delivery of technical content to the audience that requires an easy to follow demonstrator. Thanks for this as I am setting up my own homelab right now. How many cores on your Proxmox VE node? I have a Quad core Phenom II X4 with 24Gb DDR3 I want to use and Im unsure of using it in this manner..

  8. now, tell me about bond vs ovs bond without smart switch… so bonding extra nic's on each proxmox host for server to server and then fix up the isp provided public ip range (5 ip's) on one port from the ISP gateway… ugh not sure where to start… ddwrt was my friend for so long but now I need to grow…

  9. Proxmox is crap. You cannot access it on first run. I've worked with a lot of QEMU and KVM over the years, I've dealt with those problems, now I am unwilling to deal with more of those problems. Been all over the forums found little to no answers. I am unwilling to pay for support. Been down that road too many times. I'm so done with this.

  10. I am specifically looking for a training that sets up Proxmox with the intent of using it for OPNsense or pfSense. Every training I see starts with Proxmox already configured. For me I need to know how to configure Proxmox so that it has disks to upload my ISO files. I want to know how to setup Proxmox networking configuration to use with OPNsense . So it would be nice to have a tutorial that starts with a clean appliance that is ready to install Proxmox and OPNsense on. I know there are networking considerations to keep in mind and disk partioning, but I don't see any tutorials for how to configure Proxmox specifically to use it to host a firewall.

  11. Hi sir thanks for this amazing vidéo, but please make sure to make a vidéo about how to setup proxmox and configure it to use wifi adapter to be able to connect to wifi because there's no vidéo explain this point all people they use cable to connect there proxmox server please make a vidéo about wifi configuration. Thanks again
