DRBAP as an AP cannot see each other, and wireless-to-wireless traffic between the STAs is blocked.
When the setting is set to All APs in This Subnet, traffic among wireless users of different APs in the
same IP subnet is blocked. The behaviors are illustrated in the following figures.

Fig. 51. Behavior of the “All APs on This Subnet” wireless client isolation option.
As illustrated in Fig. 50 when AP 1 and AP 2 are using the “This AP Only” option, wireless traffic
between STA 1 and STA 2 is blocked by AP 1, while wireless traffic between STA 2 and STA 3,
which are associated with different APs, is still allowed. If the “All APs in This Subnet” option is
used as shown in Fig. 51, AP 1 and AP 2 communicates with each other via an inter-AP protocol to
share their STA association information to block wireless traffic among all the STAs.
There are up to 7 security modes depending on AP model variations:
