Advanced > Bridge Filters

Bridge ltering enables rules to be dened which allow or deny data to pass through

the Router based on the source and destination Bridge address and data type of

each data frame.

To access Bridge Filters Control, click on Advanced>Bridge Filters.

Usage examples of Bridge Filter Rules are: to specify which computers on a network

are allowed Internet access; or to determine which particular computers are allowed

to access services provided by the Router (the last point is particularly relevant for

routers serving Wireless Networks as it can be used to prevent unauthorised people

from attaching themselves to a wireless LAN).

Enable/Disable Bridge Filtering

To enable Bridge ltering, navigate to the Bridge Filter Control Screen and select the

Enable Bridge Filters check box.

If the check box is selected, Bridge ltering is enabled according to the list of Bridge

Filter Rules that has been created.

If the box is de-selected, Bridge Filtering will not be enabled, even if Bridge Filter

Rules have been created.

Create Bridge Filter Rules

Enter the Source Bridge and Destination Bridge details. Entering zeros or blanks

into the Source or Destination elds enters a null value.

‘Protocol’ provides the choice of protocol type for the rule.

‘Mode’ provides the choice of Allow or Deny for the rule.

When all selections are made, click on Add to add the rule to the list of rules. A

maximum of 20 Bridge Filter Rules can be dened and saved.

To save changes, click on Apply.

Edit or Delete Bridge Filter Rules
