Creating a Firewall

Scenarios

A firewall consists of one or more access control lists (ACLs). Based on inbound and outbound rules, the firewall determines whether data packets are allowed in or out of any associated subnet. You can create a custom firewall. By default, a newly created firewall is disabled. It does not have any inbound or outbound rules, nor have any subnets associated. Each user can create a maximum of 200 firewalls by default.
