IP Address and Domain limitation not working

Posted on 2012-09-22

We launched a couple of new web servers(windows 2008) and now our Intranet site that has IP limitation is accessible outside to the public.

In the older server, I installed role service for IPv4 IP Address and Domain limitation and set Feature Setting to Deny all unspecified clients.  

In the new server, the role server name is  "IP Address and Domain limitation"  Notice its' not IPv4.  However, it;s the same so I setup exactly the smae Feature Setting and add all the allow ip ranages but it's not working.  Our intratnet site is now accessible publicly.  How can I fix this?  thank you.

    I think this could be caused by Load Balancer we have for the new servers, the old one doesn't have load balance,

    With that said, is it possible to setup this intranet site on a different IP?  How to do that?  Because I have multiple site on this web server and they're all public sites.  all the sites domain are pointing to the same web server it.  how can I setup this up? thank you.

    I'm wondering, if you don't have a fireall in front of the IIS? Usually a firewall forwards (or even not requests to a webserver. Or is the IIS on a public network?

    If a load balancer is in front of the IIS farm, the filtering has to be made on the load balancer or in front of the load balancer, but may depend from the load balancer.
    You may have a look into the IIS logfiles to see, from where the IIS gets the request. I mean if you see the real client or the load balancer in the logs.

    The IIS log should clarify, why the filtering doesn' work as IIS can only filter what it gets in the request.
