.local had no problems and routes fine. It can't be looked up by public DNS servers, which is a good thing not a bad one. Yes, MS made the split horizon mistake in 2000, that was a decade and a half ago and has long since not done that. It's a horrible practice with endless problems.
Any problems with .local I'm confident were myths. Like that it could not route. It works flawlessly until you have Macs which use .local specifically to break AD as part of an MS / Apple feud from long ago.
The recommendation since .local is to have a unique domain that you own but is not .local.
Split horizon has not been considered remotely acceptable since 2003 era or earlier. There's really no upside. And as there is everything warning against it and nothing recommending it, it's quite shocking that it happens. It's the most basic thing that they have always warned about in AD training.

I am not going to put ZT or Pertino on the ownCloud server because there is zero need for it. That data is all SSL encrypted and has no need to go through any kind of other tunnel.
That makes sense. Very different from "doesn't support it"

It is also a slowdown that is not needed.

Have you tested it? is it really slower?

Yup, uses extra CPU and whatever. Shouldn't be dramatic, but it's there.

Yes Pertino is slow. Always has been. Not horrible, but slower than direct.

Has to be slower, latency is unavailable. Is it noticeably slower? That may or may not be. It will use more CPU for sure.

Kind of an average, but our Pertino would pretty typically add 50ms, which for storage can be noticed in many cases. We've seen 400ms happen a lot, but not an average. It's enough to feel for storage.

Thank you for asking the question I meant to ask

When I misconfigured Pertino once after first getting it, and the entire office was routing a single application over Pertino, it killed connections. The latency is what killed it.

Any problems with .local I'm confident were myths. Like that it could not route. It works flawlessly until you have Macs which use .local specifically to break AD as part of an MS / Apple feud from long ago.
The recommendation since .local is to have a unique domain that you own but is not .local.
Split horizon has not been considered remotely acceptable since 2003 era or earlier. There's really no upside. And as there is everything warning against it and nothing recommending it, it's quite shocking that it happens. It's the most basic thing that they have always warned about in AD training.
There are still people touting this stuff all over the place.

This site says ICANN is selling .local, but I can't find anything on that at all.

We use .local but also have a lot of macs and it sucks.
Recommendation from MS anymore is internal.domain.com or something similar

You have not been supposed to use .local for some time now, but no one is selling it, it is just a preventative measure to not have .local from that perspective. It is Apple trying to break AD is why it should be avoided. If you don't run Macs, .local works flawlessly on Windows networks.

A lot of people use ad.domain.com mostly because it is short.

That is what I use on new stuff, for exactly that reason, it is short.

Where "domain.com" is your domain, yes.

So those of you that have had a domain for over a decade, have you all moved to new domains to follow this newish domain naming.
