BRIDGE FILTERING COMMANDS
Bridge Filtering
allows you to control the packets transferred across the router. This
feature can be used to enhance security or improve performance. Filtering is based
on matched patterns within the packet at a specified offset. Two filtering modes are
available:
•
Deny mode will discard any packet that matches the deny filter database and
let all other packets pass.
•
Allow mode will only pass the packets that match the allow filter database
and discard all others.
Up to 40 deny and 40 allow filters can be activated from the filter database.
