Bonjour Gateway
Bonjour is Apple's implementation of a zero-configuration networking protocol for Apple
devices over IP. It allows OS X and iOS devices to locate other devices such as printers,
file servers and other clients on the same broadcast domain and use the services offered
without any network configuration required.
Multicast applications such as Bonjour require special consideration when being deployed
over wireless networks. Bonjour only works within a single broadcast domain, which is
usually a small area. This is by design to prevent flooding a large network with multicast
traffic. However, in some situations, a user may want to offer Bonjour services from one
VLAN to another.
ZoneDirector's Bonjour Gateway feature addresses this requirement by providing an
mDNS proxy service configurable from the web interface to allow administrators to
specify which types of Bonjour services can be accessed from/to which VLANs. In order
for the Bonjour Gateway to function, the following network configuration requirements
must be met:
• The target networks must be segmented into VLANs.
• VLANs must be mapped to different SSIDs.
• The controller must be connected to a VLAN trunk port.
Additionally, if the VLANs to be bridged by the gateway are on separate subnets the
network has to be configured to route traffic between them.
NOTE
Note the following considerations when deploying Bonjour Gateway rules.
Bridge Service Rules
The number of ZoneDirector Bonjour Gateway Bridge Service Rules that you create can
have a negative impact on memory and CPU resources.
Maximum Bonjour Gateway Rules:
• ZoneDirector 1200/3000/5000: 256
If the maximum number of Bonjour rules is exceeded, users can edit and delete existing
rules, but are not allowed to create new rules until the total number is lower than the
maximum.
Bridge Service Records
Common Bonjour Bridge Services include multiple service types, and each takes up one
service record.
Each ZoneDirector or AP serving as a Bonjour Gateway is limited to a maximum of 500
Bridge Service Records. Some Bonjour services use more than one service record. For
