Internal Server Error with web.config ipSecurity

This is my web.config which has some tags for blocking Ipaddress

<configuration>
 <connectionStrings>
    ...
 </connectionStrings>
 <appSettings>
  ....
 </appSettings> 
 <runtime>
   ....
 </runtime>
  <system.webServer>
    <security> 
        <ipSecurity allowUnlisted="false"> 
            <clear/> 
             <add ipAddress="127.0.0.1" allowed="true"/>
             <add ipAddress="83.116.19.53" allowed="true"/> 
        </ipSecurity>  
    </security>
</system.webServer> 
</configuration>

My intention is to block any other IP except the above. The above is the only Ip address I want the website to be accessible from . But with "ipSecurity" tag I am always getting 500 - Internal server error and the site runs fine without it.

I have made sure that "IP and Domains Restrictions" are installed on the server. Please let me know if I am missing anything. Thank you.

Solution

  • Are you editing the config by hand or through IIS manager?

    See this post about that error message as you may not have that feature delegation enabled
