Backend IPSecurity with Umbraco Forms

Hi everyone

I've got a page with Umbraco forms installed and a contact form set up.

Now the customer requested to lock backend access by ip address. I successfully implemented the ipsecurity feature from iis. So far this worked without a problem. But since I’ve locked the Umbraco folder for unauthorized visitors the contact form cant access the backend either. Which means the contact form won't send.

My question is, how to lock the Umbraco backend for unauthorized access but still being able to use api's on the frontend that need to access Umbraco's backend.

Any ideas?

Did you update with nuget or did you update by manually copying the files? Did you follow the version specific update guide? https://our.umbraco.com/documentation/getting-started/setup/upgrading/version-specific

Hi Timon

You can lock the access to umbraco via a web.config rewrite rule.

Add this to the systam.webServer section in your web.config.:

<rewrite>
  <rules>
    <rule name="BlockUmbracoByIP" stopProcessing="true">
      <match url="^umbraco.*"/>
      <conditions>
                    <!-- Allow access to surface and api controllers -->
        <add input="{PATH_INFO}" pattern="^/umbraco/surface.*" negate="true"/>
        <add input="{PATH_INFO}" pattern="^/umbraco/.*api.*" negate="true"/>
        <!-- External IP -->
        <add input="{REMOTE_ADDR}" pattern="<<<ADD YOUR EXTERNAL IP HERE>>>" negate="true" />
        <!--Also allow the local IP -->
        <add input="{REMOTE_ADDR}" pattern="::1" negate="true" />
        <add input="{REMOTE_ADDR}" pattern="127.0.0.1" negate="true" />
      </conditions>
      <action type="Rewrite" url="<<<PATH TO ERROR PAGE>>>"/>
    </rule>
  </rules>
</rewrite>

Hope this helps!

Cheers
