Proxmox Pi-hole Container and VLANs (Ubiquiti UniFi / LXC )

[@jonnyzeeee]

Interesting video. Nice work as always! In my testing I don't think I experienced the 5 minute delay issue described in the comments below. But when I added interfaces to the pihole server, I used Proxmox SDN so each interface had a distinct bridge. The VLAN tag is established by the SDN config.

Great video! Unifi + Proxmox is my favorite way to run things,. You can build powerful infrastructure for you home lab and/or business. As for the learning curve, with the little bit of effort and guys like you it's not as steep as it can be. Thank you!

Fantastic! Thank you. Although I've been using Proxmox (on multiple mini-pc's) for several years (running many LXC's (JellyFinn, Plex, Calibre, NginxPM, etc.) along with a large homeassistant implementation (as a VM), I haven't implemented any VLANs mainly because my current router doesn't support it. I considered using OpnSense or PfSense, but decided to go with unifi (as I already used one of their AP's and liked their controller GUI (self-hosted inside docker container)). While I wait for the delivery of my new Unifi router (cloud gateway ultra) and first unifi 16 port PoE switch, I've been trying to learn as much as possible on how to set it all up. This video helped address one question I had, "how should I configure my pihole setup to ensure it can provide DNS services to the various vlans that I intend to set up"? I know I've still got a lot to learn (which is why I did all of this), but your video helped check off a few of those 'to learn' boxes. You've got yourself another subscriber, and I'm looking forward to seeing your more of your videos (previous and upcoming). Cheers!

Thank you!

Waiting for your orbital-sync pihole and high availability video. Thank you

[@MarkConstable]

Excellent, thank you :-)

Thank for this as I was waiting for this video! I do have a question though. I understand proxmox can create vms and also containers inside vms. But is it better to manage and create the containers using portainer instead? My original idea was to install proxmox on a NUC, run 2 vms (one windows for general use and Ubuntu Vm for my apps held in docker containers) and to manage these containers using portainer. Looks like in your video, you've done this all within proxmox. Is there an advantage or disadvantage over doing it all within promox? Or have portainer manage the docker containers instead? What do you suggest? P. S this will be my first time setting this kind of thing up. I am a network engineer, just haven't done sys admin in a while so want to be sure I'm doing whatever method is most efficient and simple to manage

[@hz777]

I have not used portainer, but my understanding is proxmox is acting in the same role as portainer when it comes to managing containers. However, proxmox can do other things, such as running VMs. I am a homelabber, so an all-purpose platform such as proxmox meets my needs better.

[@DamZFXBeats]

@hz777 I see, I appreciate your perspective and insight. Thank you! I intend to use this for my home lab also, I just don't have a full on Dell server to run this on. Intend to run it on a little geekom nuc. Your videos are really helpful, keep up the great work!

hello, I just tried with installing pihole in lxc but when multiple nics are attached pihole takes 5 minutes or more to start, is it a normal behavior or I missed something?

[@hz777]

Yes I have the same experience. Don't have time to look into it to see why, but a Google search leads to some web forum posts about IPV6 DHCP.

[@HeinrichGustavio]

Thank you, exactly what I was looking for. I tried the same approach but when I remove the static IP from my vmbr0, I can't access Proxmox web UI anymore. VMs and LXCs are still accessable. With static IP in vmbr0, pihole does not start dns and pihole webui is no accessable. I have only one physical NIC. Do you have any idea?

[@hz777]

If you only have one nic, of course you should not remove the ip address from vmbr0, otherwise you will lose access to the admin UI for sure. In my case, even though it works, I need to wait for a long time (5 min?) so that pihole can start running. I don't know why. In your case, did you wait for long enough?

[@HeinrichGustavio]

@@hz777 That was it. After 6min pihole was fully started. Thank you!
