This article will see the following Create and configure a virtual cloud network(VCN) by using VCN Wizard.
By using this option VCN will create with below-added resources by default
➸ Public subnet
➸ Private subnet
➸ Internet gateway (IG)
➸ NAT gateway (NAT)
➸ Service gateway (SG)
Below are the values that need to be passed while creating VCN. CIDR ranges can vary depends on your requirement.
VCN NAME : VCN_1
COMPARTMENT : Select the appropriate compartment under List Scope in the left navigation pane.
VCN CIDR BLOCK : 10.0.0.0/17 (As per you’re requirement)
USE DNS HOSTNAMES IN THIS VCN : Checked
PUBLIC SUNBET CIDR BLOCK : 10.0.0.0/24 (As per you’re requirement)
PRIVATE SUBNET CIDR BLOCK : 10.0.1.0/24 (As per you’re requirement)
As a Public subnet we can have access to the internet, a Private subnet we can have an inbound connection for preferred IPs but not outbound connections.
As a 2nd step review the resources that are creating.
Subnets, Internet gateway (IG), NAT gateway (NAT), Service gateway (SG)
Once the review is done Click on create it will re-direct to the VCN page which will display resources that are created through the wizard
