Web Mail Not Working After Adding New DNS Zone

@Kelly said in Web Mail Not Working After Adding New DNS Zone:
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.internalIs of course is the best solution when using Split Horizon DNS because if the internal IP changes, the records will all follow.
-
so whoever hosts the DNS for my domain should be able to create a CNAME to alias owncloud.roseradiology.com to owncloud.rose.internal? Correct?

No, that is something you would do internally, on the DNS servers you control. In a Split Horizon setup, the two systems, internal DNS and external DNS, they both are handled completely separately.
But, internally, where you have both rose.internal and roseradiology.com, you can create a record from one domain pointing to the other if you want.

So if I add a record for mail.roseradiology.com that should fix?
Yes, but it's far from ideal.

but that would direct ALL external users to the same internal IP address causing them to fail.

he's talking about doing this on his INTERNAL DNS server, I do believe.

people don't normally refers to the internal staff as "whoever hosts my..." That's an odd terminology to use for the guy at the desk next to yours.

Or your own desk.

Yes, but if you recall (or go look at) the prior thread, it is clear that he has no understanding of DNS at all.

For example:
A 192.168.1.5 ownlcloud.rose.internal
CNAME owncloud.roseradiology.com owncloud.rose.internalI did not think Windows let you do that
-
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

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
-
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 ?
-
yes, everything is working today. and so is owncloud from the outside.
-
i have different URL's for owncloud inside the network and owncloud outside the network but that should be ok.
