Update the Default Security List for the VCN

Follow this procedure to update the default security list for the VCN to allow necessary traffic.

Earlier you set up the subnet to use the VCN's default security list. Now you add security list rules that allow the types of connections that the instances in the VCN will need.

To update the default security list for the VCN, perform the following steps in the your new compartment:

1. While viewing the VCN, under Resources, click Security Lists.

   Note -  For more information, refer to the relevant OCI documentation here.

2. Click the default security list to view its details. By default, you land on the Ingress Rules page.
3. Click Add Ingress Rule.
4. To enable inbound connections for HTTPS (TCP port 443), enter the following:

   Stateless: Unselected (this is a stateful rule.)

   Source Type: CIDR.

   Source CIDR: 0.0.0.0/0

   IP Protocol: TCP

   Source Port Range: All

   Destination Port Range: 443

5. Click Add Ingress Rule.
6. Use the above steps to add a stateful ingress rule for any subnets with customer assets for the protocols/ports listed in Oracle Advanced Support Gateway Security Guide.
7. Add a stateful ingress rule for Oracle's JumpGate Host for TCP Ports 22 and 443.
