Configuring Firewall Settings to Disable Auto Topology Rules
By default, the auto topology rules in an IAP are enabled. You can disable the rules by configuring firewall
settings in the IAP.
In order to deny auto topology communication outside the IAP subnet, the inbound firewall settings must be
enabled.
When the inbound firewall settings are enabled:
l Access Control Entities (ACEs) must be configured to block auto topology messages, as there is no default
rule at the top of predefined ACLs.
l ACEs must be configured to override the guest VLAN auto-expanded ACEs. In other words, the user defined
ACEs take higher precedence over guest VLAN ACEs.
For more information on inbound firewall settings, see Managing Inbound Traffic.
The priority of a particular ACE is determined based on the order in which it is programmed. Ensure that you
do not accidentally override the guest VLAN ACEs.
You can change the status of auto topology rules by using the Instant UI or the CLI:
In the Instant UI
1. Click the Security located directly above the Search bar in the Instant main window.
2. Go to the Firewall Settings tab.
3. In Firewall section, select Disabled from the Auto topology rules drop-down list.
4. Click OK.
In the CLI
(Instant AP)(config)# firewall
(Instant AP)(firewall)# disable-auto-topology-rules
(Instant AP)(firewall)# end
(Instant AP)# commit apply
