Bridge Filters
Bridge filters are used to block or allow various types of packets through the WAN interface. This may be done for security or to improve network efficiency. The rules are configured for individual devices based on MAC address. Filter rules can be set up for source, destination or both. You can set up filter rules and disable the entire set of rules without loosing the rules that have been configured.
Bridge Filters window
To add a bridge filter rule, check Enable Bridge Filters, type in a Source MAC, a Destination MAC or both in the entry fields, you may opt to limit filtering to only the Ethernet, and click the Apply button. To remove a bridge filter from the table in the bottom half of the window, click the corresponding trashcan icon. Remember to save the configuration changes.
The protocols that may be specifically allowed or denied to pass through the WAN interface are the following: IPv4, IPv6, RARP, PPPoE Discovery and PPPoE Session.
