Manage Firewall Control Parameters

1. To enable or disable the IPv4 firewall control feature, at the config:# prompt, type security ipAccessControl ipv4 enabled <option>, and press Enter.
2. To enable or disable the IPv6 firewall control feature, at the config:# prompt, type security ipAccessControl ipv6 enabled <option>, and press Enter.

   <option> is one of the options:

   • true – Enables the IP access control feature.

   • false – Disables the IP access control feature.

3. To determine the default IPv4 firewall control policy for inbound traffic, at the config:# prompt, type security ipAccessControl ipv4 defaultPolicyIn <policy>, and press Enter.
4. To determine the default IPv6 firewall control policy for inbound traffic, at the config:# prompt, type security ipAccessControl ipv6 defaultPolicyIn <policy>, and press Enter.
5. To determine the default IPv4 firewall control policy for outbound traffic, at the config:# prompt, type security ipAccessControl ipv4 defaultPolicyOut <policy>, and press Enter.
6. To determine the default IPv6 firewall control policy for outbound traffic, at the config:# prompt, type security ipAccessControl ipv6 defaultPolicyOut <policy>, and press Enter.

   <policy> is one of the options:

   Policy Description accept Accepts traffic from all IP addresses. drop Discards traffic from all IP addresses, without sending any failure notification to the source host. reject Discards traffic from all IP addresses, and an ICMP message is sent to the source host for failure notification.

7. For example, to combine both commands to modify all firewall control parameters at a time, config:# prompt, type security ipAccessControl ipv4 enabled true defaultPolicyIn accept defaultPolicyOut accept, and press Enter.

   • IPv4 access control feature is enabled.

   • Default policy for inbound traffic is set to accept.

   • Default policy for outbound traffic is set to accept.
