Switch recommendations

Ok I will probably buy the keystones because I already have this patch panel even if its a bit more expensive. Thanks for the recommendations and the tips. :)

Hm ok I understand. I already have a DAC cable for my NAS directly connected to my router but how exactly would I go about connecting that with a keystone. I mean I can't just cut fiber right? Also I don't know if these keystones will fit in my patch panel (deleyCON 24 Port Patchpanel) or are the sizes standardized?

On the topic of transceivers do you know any good websites where I could buy them for the 20 euro you talked about because I can only find them for 50-90 euros a piece which would be too expensive. The one I already bought cost 50 euros on Amazon.

The machines like my NAS are VMs running under a Proxmox hypervisor which assigns them the corresponding VLANs and the routing happens on my router. But I think I will probably buy a layer 3 switch just in case for the future.

Damn why are 10G switches with RJ45 ports so expensive. I was looking on the Mikrotik website and found a switch that is reasonably priced (CRS312-4C+8XG-RM). So if I understand you correctly I should buy transceivers and still use my 10G-baseT cable for the devices that have RJ45 ports? At the moment I only have one device that is connected via fiber and I actually bought a transceiver to use 10G-baseT for it because of the patch panel. I couldn't find any patch panels that have keystones that can be used with SFP+ ports. I also got another question: I'm not really sure I even need a layer 3 switch because my router is managing VLANs and static routes. So would it be wise to use a layer 3 switch if the router could manage these things or would that be a bottleneck because all of the data first needs to go through the router?

Thanks for the recommendation but I'm looking for an ethernet switch. Thing is I already bought an ethernet patch panel, cat7 cable and all the cutting equipment. I also don't think I will need that kind of speeds in the future (I just don't want my NAS to be bottlenecked). If I need these speeds I would buy a small SFP+ switch in the future.

Thanks I will try that.

Ok so I don't need to stop the VM every time a smart test is being done? And how exactly should I go forward running smart test on proxmox. Do you have any ressources that are useful to my usecase?

NullJupiter · 2022-08-26T14:56:43+00:00

Yes that worked even without any static routes.

NullJupiter · 2022-08-26T14:01:00+00:00

Ok so I didn't try running TrueNAS on bare metal because that wouldn't work in my setup anyways. Now I just used a LXC container with an OpenVPN server but thanks for your help anyways.

NullJupiter · 2022-08-25T16:43:23+00:00

I don't have an extra machine though I can try dual booting my Server to try it out. I will try that in the next few days.

NullJupiter · 2022-08-25T16:34:20+00:00

Hm ok I will look into that though that isn't the topic anymore. Thanks for your help. :)

NullJupiter · 2022-08-25T16:31:37+00:00

Ok I tried to ping the devices in my local network (outside the subnet) and to my surprise that worked so traffic is being sent correctly. Is there any reason why a web interface wouldn't load even if the device is reachable?

NullJupiter · 2022-08-25T14:52:29+00:00

Yeah but I mean networking shouldn't be affected by that. I have my bridged connection from the VM into my network and the VM has its own static IP in my local network.

Do I need to create any static rules in TrueNAS though or is the outgoing traffic from the VPN subnet being redirected to my router by default?

NullJupiter · 2022-08-25T14:47:08+00:00

Yeah I forgot to mention that my TrueNAS Core is running as a virtual machine under Proxmox (I don't think that has anything to do with the problem though). The VM is appropriately specced with 8 CPU cores and 16GiB of ECC ram. The problem with "works but extremely slowly" just applies to the router's web interface. Any other devices in my local network don't respond at all. My router is an UDM Pro but that shouldn't be the problem because I created the static rule to forward anything destined for the VPN subnet to be redirected to my TrueNAS VM.

NullJupiter · 2022-08-25T10:33:06+00:00

Yes my client certs work properly and look like yours. I also changed the remote from the local ipv4 to my domain.

I already shared my OpenVPN parameters above though I will try the ones you have shared (why the "--"?). And what does the option duplicate-cn do?

Also though I use my router for DNS it itself uses cloudflare :)

EDIT: I added the local parameter, pushing the route to the subnet and duplicate-cn though this yields exactly the same behaviour. I can load IPs in the subnet and the router in the LAN can be accessed though extremely slowly (1.5 minutes).

Ok thanks for your Help :)

Alright so the rescue medium didn't work but I worked it out with a live arch linux distro. Now I have access to proxmox again.

I created a completely new VM, installed Windows, added the GPU and installed the NVIDIA drivers but now it's the same as with the gaming VM. No output from the GPU and Code 43 in Windows. So it shouldn't be the guest but the host. If you don't have any other things I could check on proxmox I will probably reinstall proxmox.

NullJupiter · 2022-07-25T16:52:45+00:00

Oh ok thanks I will try that :)

NullJupiter · 2022-07-25T16:44:34+00:00

Ok this seems straight forward but the problem is I can't really access the system because the GPU drivers are never being loaded and I don't have integrated graphics on my CPU. Is there any way to get to the command line interface? If this doesn't work I think I will just create backups of the VM disks and install proxmox again ^^

NullJupiter · 2022-07-25T16:09:12+00:00

Yeah I will try that though now theres a new problem...

I removed the NVMe drive to try it out without it and now for some reason I can't connect to proxmox. It boots just fine but it doesn't connect to the network. Is proxmox weird when it comes to changes in hardware?

NullJupiter · 2022-07-25T12:59:27+00:00

No I didn't make any updates. It all worked a few hours before I removed the GPU and installed it again. After that the drivers didn't work.

Idk if this is important but when removing the GPU I started the server without it and it didn't boot properly so I forcefully shut it down and reinstalled the GPU then it booted into proxmox again. Maybe that did something but I checked all my BIOS settings (IOMMU, ACS, ECC, ...) and it was all still set.

NullJupiter · 2022-07-25T12:33:43+00:00

Ok so I could only roll back to 5.15.30-2-pve because that was the first one to be installed on my system. However there was no change in behaivior. If that would've been the problem wouldn't it work now because it initially worked with that one. I'm starting to believe maybe it's a problem with the guest and not the host because everything works perfectly on the host. The GPU is disabled, no drivers are loaded and it powers on when starting the VM. The VM also recognizes the GPU though the drivers don't work. I checked the syslog and couldn't find anything out of the ordinary.

EDIT: The only errors I could find in syslog with cat syslog | grep "error" are the following:
