ZeroTier Question
-
Are their email address - [email protected]
and your email address - [email protected]?If so, those are two different DNS MX records. They can each go anywhere you want them to.

That is correct. Exchange works fine as it is. I was just wondering if *.wels.net was getting sucked into Office 365 somehow.
We have noticed a few issues with people who are trying to access their Microsoft Accounts getting errors saying that there is no account for them at WELS Cloud.

I would think in your case, you wouldn't want to have a *.wels.net record because of problems like this.

Sorry - I meant the * as wls.wels.net

Sounds like you have a DNS issue. You might not be able to use short NetBIOS type names.. you might have to move to FQDN instead.
For example, if you're at StarBucks and the DHCP server gives a suffix of starbucks.com out with the IP, and you ping server1, your system might be pinging server1.starbucks.com instead of server1.yourdomain.com
I missed this or it didn't click. So you're saying that I might have to go to wls-dc01.wls.wels.net instead of WLS-DC01, correct?

Also, if I ping another server from off site I get this:
-
You need to go into the NIC settings for your ZT adapter and specify the ZT IP address of you internal DNS server...
What is happening is your ping / nslookup from off-site is using whatever DNS servers your ISP gives you.
Both of the IP addresses that I pointed to are the ZT IP addresses of my internal DNS servers.

This goes back to what I was saying earlier though... Your AD servers may have two IP addresses for everything... so if you ping ad01.mydomain.net, you might get the internal IP address... and that is fine if you are on site.
If you are off-site and your DNS server returns the internal IP, stuff still ain't gonna work.
Edit: Thanks for the Kudos.

@dafyre I got the onsite vs offsite part. However, shouldn't ZeroTier handle the offsite routing? Or is that not how this works

ZT will only run traffic across its NIC that falls on the ZT IP Range. So if you DNS Server returns 172.16.10.100 and your ZT Network is 192.168.100.x ... Your ZT Network won't know how to get you to the 172 network.

It's not about handling routing because there would be no route.
Example
Server internal wire network IP - 192.16.8.10
________________________ZT IP - 10.0.50.10If, when you're offsite, DNS returns the 192.16.8.10 address, the ZT network would never look at this traffic because it's not part of the ZT network. Instead that traffic would go to the normal NIC, wireless probably, and go out that way and of course fail.

Yes this is exactly what I meant.

Also, if I ping another server from off site I get this:
WOW - how does that happen? What is returning that IP address? I wonder if the coffeehouse server is returning bad info?

And this is why I default to building a ZT Gateway. Yes, it is more work up front. Yes, it is slightly more complicated. However, it prevents you from having to deal with these types of issues.

You probably need to ipconfig /flushdns ?

This is from a single user at his home.

If I put the ZT IP Addresses in the ZT NIC I won't need to do this, yes?

But where did the 198.105.x.x IP come from? that is not anywhere on the OP's network (that we know of). When I ping that FQDN here I get could not fined host.
