Technical explanation

A user role is the attachment point for one or more firewall policies, and every policy consists of an ordered sequence of match/action rules. Match criteria can involve source/destination objects, protocols, ports and application identification; outcomes can include allow, deny, redirect or additional traffic treatment. Evaluation order matters because broader permissions placed before a specific restriction can defeat the intended access boundary. Verify the role assigned by AAA and whether the enforcement location is the AP, switch or gateway before assessing effective security behavior. Consider a role named GUEST: it references an internet-access policy, whose first rule denies RFC1918 management networks and later rules allow required services. Changing the policy changes the role’s effective forwarding behavior.

Rules do not contain nested policies; roles do not reference loose rules independently of policy organization. Nor do policies “inherit” role membership in the reverse direction. Roles bind policy objects, and each policy evaluates an ordered sequence of matching rules.

Technical explanation

The rule is a logarithmic shortcut. A 3 dB gain multiplies linear power by 10^(3/10), approximately 1.995, so 1 mW becomes about 2 mW. In dBm, that is 0 dBm to roughly +3 dBm. A tenfold power increase requires +10 dB, not +3 dB. Negative 3 dB approximately halves power; negative 10 dB reduces it to one-tenth. The question is about power ratio, not a guarantee of twice the Wi-Fi range.

Technical explanation

The client's Events card builds a chronology of connection transitions, enabling operators to correlate disassociation, failed authentication, roaming and IP address assignment. Preserve the client's MAC address and the interval under review because randomized MAC behavior can make a user appear as multiple identities. A device configuration page shows intended WLAN settings, and the RF dashboard captures environmental data, but neither provides the direct per-client event sequence. Use the timeline to identify the first failing stage before investigating downstream services.

RF Health aggregates environmental conditions; AP Configuration describes intended parameters. The client Events card is concerned with time-stamped association, authentication and disconnection activity, the sequence needed to diagnose one station.

Technical explanation

With tunneled client forwarding, gateway policy becomes a consistent enforcement point for branch WLAN clients. Authentication, role assignment, user VLAN anchoring and traffic inspection can be coordinated centrally, while individual branches retain relatively modest local VLAN requirements. Check WAN latency, gateway cluster capacity, tunnel redundancy and failure behavior before choosing this architecture. Bridging all traffic locally can be valid in smaller branches, but it decentralizes the datapath and reduces the central inspection consistency stipulated by the scenario. A branch design using tunneled traffic also requires sufficient WAN capacity and a survivability plan. Centralized inspection is beneficial only when the gateway and transport remain appropriately available.

Bridge mode breaks out traffic at the AP and may enforce policy locally, so adding gateways without tunnel forwarding does not centralize inspection. Standalone APs lack the requested shared gateway datapath. A tunneled design consolidates enforcement at the gateway cluster.
