Web Mail Not Working After Adding New DNS Zone

[JaredBusch]

For you internal DNS server, you have to now setup everything to match what your external DNS shows, except for the items that you want to point to internal addresses.

Here is a live working example from a client

Internal DNS for domain.com

External DNS for domain.com

What about creating a CNAME that points to the internal A record?

For example:

A 192.168.1.5 ownlcloud.rose.internal
CNAME owncloud.roseradiology.com owncloud.rose.internal

I did not think Windows let you do that

You absolutely can do this.

Of course you can add a CNAME to an existing zone. I thought @Kelly was saying to add a CNAME for owncloud.roseradiology.com without adding roseradiology.com as a forward lookup zone.

That was what I thought you could not do.

huh, yeah I would guess you couldn't do that either, again, if you're not hosting the zone you want to Cname to, you can't do it.

Interestingly enough, it lets you add it, but it does not work.

owncloud.domain.local resolves to 10.201.1.17

[Dashrender]

Of course it doesn't work - the system isn't authoritative for the daerma.com domain, so it wouldn't even look for that entry.

What would be interesting though is the opposite, junk.xxxxxx.local -> oc.daerma.com

Which should work.

Cname did the trick. Thanks everyone.

Did you add the records for the rest of your public services on roseradiology.com ?

[alex.olynyk]

yes, everything is working today. and so is owncloud from the outside.

[alex.olynyk]

i have different URL's for owncloud inside the network and owncloud outside the network but that should be ok.

It should be OK as long as your users know which to use where.

It is? What if they want to share a file?

Well, that is a problem, probably.

Is there a reason you don't them the same inside and outside?

With DNS you can do this easily.
