Abstract
Example methods are provided for a firewall controller to implement a distributed firewall in a virtualized computing environment that includes a source host and a destination host. The method may comprise retrieving a first firewall rule that is applicable at the destination host to an ingress packet destined for a destination virtualized computing instance supported by the destination host; and based on the first firewall rule, generating a second firewall rule that is applicable at the source host to an egress packet destined for the destination virtualized computing instance. The method may further comprise instructing the source host to apply the second firewall rule to, in response to determination that the egress packet is blocked by the second firewall rule, drop the egress packet such that the egress packet is not sent from the source host to the destination host.
