    <tt>Hi Sunil,<br>
      <br>
      You can use the {ip.matches} transformation to check the IP
      against the RFC1918 subnets<br>

        <div dir="ltr">Hi All,
          <div><br>
          </div>
          <div>I am using a setup on GCP with advertised IP address. It
            will be used as an edge proxy to send/receive calls. I have
            a VPN client connecting directly to the GCP instance on its
            private interface. </div>
          <div><br>
          </div>
          <div>I want to forward inbound calls to clients. While doing
            this I want to identify if the forwarding IP is private IP
            (RFC1918) or public IP and likewise use the advertised IP
            address. How can I do this ?</div>
          <div><br>
          </div>
          <div>Regards,</div>
