bridging).WDS may be incompatible between different products
(even occasionally from the same vendor) since it is not certified
by the Wi-Fi Alliance. WDS may provide two modes of wireless
AP-to-AP connectivity:
Wireless bridging, in which WDS APs communicate only with
each other and don't allow wireless clients or stations (STA) to
access them.
Wireless repeating, in which APs communicate with each other
and with wireless STAs.
DMZ
In computer security, a DMZ (sometimes referred to as a
perimeter networking) is a physical or logical subnetwork that
contains and exposes an organization's external-facing services
to a larger untrusted network, usually the Internet. The purpose
of a DMZ is to add an additional layer of security to an
organization's local area network (LAN); an external attacker
only has access to equipment in the DMZ, rather than any other
part of the network. Hosts in the DMZ have limited connectivity
to specific hosts in the internal network, although
communication with other hosts in the DMZ and to the external
network is allowed. This allows hosts in the DMZ to provide
services to both the internal and external network, while an
intervening firewall controls the traffic between the DMZ servers
and the internal network clients. Any services such as Web
servers, Mail servers, FTP servers and VoIP servers, etc. that are
being provided to users on the external network can be placed in
the DMZ.
