1.2.3 AP + Bridge

In AP+Bridge mode, the ZyXEL Device supports both AP and bridge connection at the same

time.

In the figure below, A and B use X as an AP to access the wired network, while X and Y

communicate in bridge mode.

When the ZyXEL Device is in AP + Bridge mode, security between APs (the Wireless

Distribution System or WDS) is independent of the security between the wireless stations and

the AP. If you do not enable WDS security, traffic between APs is not encrypted. When WDS

security is enabled, both APs must use the same pre-shared key. See Section 6.7.3 on page 98

for more details.

Unless specified, the term “security settings” refers to the traffic between the wireless stations

and the ZyXEL Device.
