  • Reverse proxy configuration

    Mar 25, 2020 10:57 AM|DRDG|LINK


    I have the following scenario for one of my customers and I can't figure out how to get it working.

    1 internal IIS with ~hundred of sites that needs to be published online

    1 DMZ IIS with ARR installed

    All of the websites on the internal IIS has the following bindings:

    And so on...

    How can I get the IIS in the DMZ to act as a reverse proxy for all these sites? I have tried some different configurations but I always end up being redirected to the internal IIS Default Website no matter what URL i use. 

    Thank you!

    Hi DRDG,

    For example, if you have an external domain and you want to reverse proxy it to

    1.You need to create a website in DMZ server. 

    2. Creating a binding host header of your external domain

    3.Make sure the website can be accessed from external and your DMZ server is able to access internal website.

    4.Enable proxy in IIS manager->server node-> application request routin cache->Server proxy settings->Enable proxy.

    5.Create a rewrite rule to based on your server

      <rule name="reverse proxy">
                        <match url="(.*)" />
                            <add input="{HTTP_HOST}" pattern="" />
                        <action type="Rewrite" url="{R:1}" />

    You can use single DMZ website to distribute requests. As long as you create multiple binding host header with different host name and filter the rewrite rule based on {HTTP_HOST} variable.
