Custom IP Filter Rules
You can configure the SpeedStream Router firewall to perform IP filtering and stateful inspection of packets. The firewall supports a rules database to allow sophisticated access tailoring. A network conversation is first authorized by verifying the packet against the current rules database configured within the firewall. If the first packet of a conversation is allowed, then a dynamic state engine takes over and tracks that conversation. All protocols are tracked whether they are
The filtering rules database gives you control over the configurable firewall rules. Rules can be filter- based on any of the following:
•Source and destination router interfaces
•IP protocols
•Direction of traffic flow
•Source and destination network/host IP address
•
•Source and destination port ranges (for protocols that support them), and support for port comparison operators such as less than, greater than, and equal to.
Rules can specifically allow or deny packets to flow through the router. Default actions taken when no specific rule applies can also be configured.
Note You must have previously selected Custom Level in the Firewall - Simple Setup & Control
screen.
