Abstract
Various embodiments of the invention disclosed herein provide techniques for associating a firewall policy with a dynamic domain name system (DNS) hostname. A policy configuration portal associates a first hostname with a first network address. The policy configuration portal sets firewall policy configuration associated with the first hostname to include the first network address. The policy configuration portal receives a first message that associates a DNS hostname with a second network address. The policy configuration portal, in response to receiving the first message, associates the second network address with the first hostname. The policy configuration portal modifies a firewall policy configuration associated with the first hostname to include the second network address. At least one advantage of the disclosed techniques is that a firewall policy can be implemented for a residential home or small business that employs dynamic IP addressing.
