Need iRule to Redirect TLS 1.0 Traffic to Maintenance Page

Hello,

 

We will be disabling TLS1.0 on our SSL client profiles in the cipher section using: "DEFAULT:!SSLv3:!RC4:!TLSV1"

 

We do still see traffic coming in though so want to create an irule to redirect that traffic to a maintenance page that will provide links to sites that will tell them how to adjust their browser settings.

 

I'm looking for someone to help me write that rule as I don't know how to start.

 

Thanks in advance!

 

Diane

    Hello,

    Try the following irule 

    when HTTP_REQUEST {
    if { [SSL::cipher version] eq "TLSv1" } {

        HTTP::respond 200 content {
          
             
                Apology Page
             
                
                    We are sorry, but the site you are looking for is temporarily out of service
                    If you feel you have reached this page in error, please try again.
                
          
        }
    } else {
      log local0. "SSL Protocol version  [SSL::cipher version]"
    }
}

    Hope it helps

    Regards

    Please use the following irule (copy it as it is 😄

    when HTTP_REQUEST {
    if { [SSL::cipher version] eq "TLSv1" } {
       HTTP::respond 200 content [ifile get "/Common/NoTLSv10_iFile.html"] noserver "Content-Type" "text/html" "Cache-Control" "no-cache, must-revalidate" "Connection" "Close"
    } else {
      log local0. "SSL Protocol version  [SSL::cipher version]"
    }
}
