Masking an internal network redirect with IIS?

Posted on 2016-07-25

I've got a sub-domain set up externally with masking that to goes a blog another group in our company is using.  I've created a sub-domain at our domain host of that redirects to - but is masked as  No problem there.

What our employees see while at work is why I'm asking this question.  Because of the /company in the url, I know I can't do anything with the internal DNS like I usually would and I don't have an ip address for the blog site to point to.  I created an internal web site in IIS so I can do url rewrites or redirects but the address in browser always resolves back to - so that's what our staff sees.  While this isn't especially bothersome to me, I know the question will come as to why we can't show internally as well?  I've got the URL Rewrite and ARR modules installed but am struggling to make sense of it all and am not sure if what I'm looking for is possible.

So that is my question - is there anything I can do in IIS so what while at work, when our employees go the blog site, they see in their browser instead of like they do now?

I hope this is clear - as always, thanks in advance.

You don't need URL Rewrite or ARR.

1.  Do you have only 1 IIS box?
2.  Is the blog content on this IIS server
3.  Are you running AD?
3a.  If yes, is your AD domain name?

Just setup an new internal site and point the root of the site to the location of the blog content.  This assumes that the content of the blog is on the same IIS server.

In DNS just create a CNAME pointing to the IIS servers internal name.  Use host names on the site bindings to point to the internal ip and use the CNAME created.

Sorry - I didn't provide all the info - still somewhat new at this part.  Hopefully this will clear it up.

We have multiple servers in house, including 3 large VM hosts - 2 for internal applications and 1 for web applications and sites in a DMZ.  So, multiple instances of IIS running on the different web servers we have for various thing.  We run AD and have an internal DNS.  For the sake of this question, let's just say our domain name is

The blog is hosted on an external site at and that's where the problem begins as the address is:

The '/' in the blog address, prevents me getting an ip address for an ANAME record and also makes it impossible to use a CNAME record as well. I've done multiples of those in other scenarios - it's the '/' that has me stumped as to what to do.

At the moment, I have a subdomain of set up on our domain host that redirect to wix and masks the address.  Internally, I have an internal web site bound to  that simply redirects internal traffic for to  

What I need to know is if there is a way to configure IIS to mask the address like our domain host does so that our internal customers see instead of the wixsite address.

I hope that is clearer than before - my apologies for the confusion.

What are you using for your AD domain name?

Why not just let your internal users hit the external site directly?

Sorry for the late response - we've been short-handed and it 'other duties as assigned'.

Our only domain is the  We've been trying to figure out why we can't simply go there - don't know if its something with the firewall or something else - it's always been thus.  Problem is, the guy who built everything died a little over an year ago and had not shared all the details.  We've come to find out that a lot of it is pretty ad-hoc so there may not be an easy solution for this like I hoped.

I appreciate your time however - at the moment, I have to close this as I need to concentrate on some other projects for the next couple of months.
