+1. Configure access to the instance from your local machine
+
+   * On your local machine, open a browser and find your public IPv4 address using a serivce like [ShowMyIP](https://www.showmyip.com/).
+
+   * In the OCI Console, when viewing your compute instance, click on the link for the subnet in the **Prinary VNIC** section.
+
+   * On the subnet page, click on the link for the Default Security List.
+
+   * Click on the **Add Ingress Rules** button to create a new Ingress Rule.
+
+   * Complete the form by specifying the **Source CIDR**.  Make this as specific as possible, ideally just your one machine by specifying the IP address you just collected with the suffix `/32` added.  Set the **Destination Port Range** to `443`, and add a description if you wish.  The completed form should look like this (in this example your machine's IP address was `1.2.3.4`):

+   * On your local machine, open a browser and navigate to the Spring Operations Center using the IP address of your instance, for example, if you instance is `1.2.3.4`, then the address will be `https://1.2.3.4/soc`.
