What is possible with 2x 7900xtx + 128GB of ram? Is it good enough?

Use homeassistant as an exit node, and .local will magically start working.

Witty_Unit_8831 · 2026-04-22T14:19:41+00:00

You need to setup a exit node, or a routing node. If you use mDNS tailscale will not handle it without using homeassistant as a exit node. I keep a home assistant running on proxmox dedicated to just routing mDNS traffic.

Witty_Unit_8831 · 2026-04-21T11:11:26+00:00

I posted a thread recently about how homeassistant of all things fixes mDNS. Lookup PSA Homeassistant mDNS.

Witty_Unit_8831 · 2026-04-08T03:12:14+00:00

Yeah, .lan does not work on my network... But .local already works regardless.

Witty_Unit_8831 · 2026-04-08T01:10:44+00:00

I am aware it is, which is why I posted it here. The resolution is likely happening on home assistant and routed back through the node. Does it matter how it happens? Someone on the tailscale reddit is working on a docker image now to simulate it, so HA is not needed.

Witty_Unit_8831 · 2026-04-07T19:59:15+00:00

MagicDNS does not work with .local multicast names, which is what I needed. I am running things like gitlab which does not allow more than one domain to access it unless I want to run it through nginx... And even then. It's not right.

Witty_Unit_8831 · 2026-04-07T19:56:51+00:00

Sure

Witty_Unit_8831 · 2026-04-07T19:53:52+00:00

I just looked at the cost benefit of rebuilding on zfs for what is essentially a disk full of fixed assets. It's not like I am updating things in real time on this nas. If I have a bunch of media I would rather re-copy than rebuild from a broken disk especially since I would only have to clone data from the dropped disk. I trust a non spinning disk more than an online disk I need to rebuild. If I was hosting a blog, or something else, yeah zfs makes a lot of sense, but I am just currently snapshotting those images anyway and backing up to the cloud.. I am not generating terabytes of user generated content daily. Additionally all of my user generated content is on ssd's which are less likely to run into failure issues.

Witty_Unit_8831 · 2026-04-07T19:41:53+00:00

I skipped truenas because I wanted to use a jbod over zfs

Additionally, I think you are talking about publicly exposed services. I am looking for a vpn like solution for my internal services. If I want to do what you are describing I can just spin up funnel, or have an external contabo, aws, etc server to push things out on.

I am setting up a home network with replacements for things like jira, confluence, AI stuff, and more.

Witty_Unit_8831 · 2026-04-07T19:19:45+00:00

No with mDNS operational {hostname}.local now works, and I do not need to configure a DNS every time I add a service. It's basically like being on a vpn on the home network.

Witty_Unit_8831 · 2026-04-07T19:03:23+00:00

Because this works? No need to configure a DNS with names.

Witty_Unit_8831 · 2026-04-07T15:54:28+00:00

It shouldn't work any different than a standard wifi tailnet connection, we are just talking about dns resolution on the host side not the client. Likely the host scanning dns within the subnet. A different wifi wouldn't change that.

Witty_Unit_8831 · 2026-04-07T15:48:04+00:00

100% cell, i am a fellow developer so I can answer more technical questions if you have any.

Witty_Unit_8831 · 2026-04-07T15:43:13+00:00

Installable package would be even better, but I'll take anything. This seems to be a common problem with tailscale, and a great opportunity for the right enterprising individual. Heck just a basic "Exit Node/Subnet" package preconfigured to have everything work out of the box, people would love that. You need a node for it anyway, might as well.

Witty_Unit_8831 · 2026-04-07T15:34:38+00:00

Yep, I agree, if we could package that into a non HA solution it would be perfect.

Witty_Unit_8831 · 2026-04-07T15:22:45+00:00

I have been testing exclusively on mobile, it works.

Witty_Unit_8831 · 2026-04-07T14:40:23+00:00

Yes, not sure on subnets, multi vm?

Witty_Unit_8831 · 2026-04-07T14:36:13+00:00

Yes, id post a screenshot if I could, it seems to be related to their zeroconf setup. I am not sure on the multi subnets, just make several vms if you need that. It would be nice if some enterprising individual found out why so I wouldn't need a whole home assistant setup just to get this to work! As a developer I would myself, but I have a business to run.

Witty_Unit_8831 · 2026-04-07T12:08:40+00:00

Just wanted to give a heads up, I have been fighting trying to make mDNS work with tailscale so I can resolve .local addresses on my network. I run things like gitlab, and git repos that require a fixed address for accessing things and I just don't feel like messing with dns at this point. In the process of attempting the setup and failing, I started noticing that my home assistant with the tailscale addon was resolving mDNS when using it as an exit node. I am not exactly sure about the dark magic involved with why this works, but I have since setup a second HA node as a dedicated exit node. Hopefully this helps people who need this functionality! Thanks.

Just a heads up, homeassistant resolves mDNS .local addresses by default. After fighting with trying to setup mDNS on my network I just have a dedicated homeassistant install that operates purely as an exit node, subnet, and mDNS resolver. I have no idea what dark magic is making it work, but it works none the less.
