Public/guest network access
Global access control settings
Note Location change is not supported for locally authenticated users.
Maximum concurrently authenticated public access users
Specify the maximum number of users that can be authenticated and logged into the public
access interface at the same time.
Client polling
The service controller continually polls authenticated client stations to ensure that they are
active. If no response is received and the number of specified retries is reached, the client
station is disconnected. To use this feature, client stations must have L2 connectivity to the
service controller.
This feature enables the service controller to detect if two client stations are using the same
IP address but have different MAC addresses. If this occurs, access is terminated for this IP
address removing both stations from the network.
Changing these values may have security implications. A large interval provides a greater
opportunity for a session to be hijacked.
The initial query is always done after the client station has been idle for 60 seconds. If there is
no answer to this query, the settings for Interval and Retries are used to control additional
retries.
Polling interval
Specify how long to wait between polls.
Consecutive retries
Specify how many consecutive polls to which a client station can fail to reply before it is
disconnected.
Zero configuration
These settings apply to client stations that are authenticated by the service controller for
VSCs that have access control enabled.
Support users that have a static IP address
Enable this option to allow client stations with static IP addresses that are not on the same
subnet as the service controller to connect to the service controller. This permits users to
access the network without reconfiguring their network settings.
For example, by default the service controller creates a network on the subnet 192.168.1.0. A
client station that is preconfigured with the address 10.10.4.99 can connect to the service
controller without changing addresses.
Assign addresses on the Public Access subnet: Enable this option to provide network
address translation for client stations with static IP addresses. This permits the service
controller to assign an alias address to the client station that puts it on the same subnet as
the VSC the client station is associated with. This subnet is defined by configuring the
DHCP server option in the VSC.
