Firewall Stateful Inspection Table
The Firewall Stateful Inspection table is a sophisticated, scripted stateful firewall and route
inspection engine. Stateful inspection is a powerful tool allowing the router to keep track of a TCP/
UDP or ICMP session and match packets based on the state of the connection on which they are
being carried.
The table contains a list of dynamic firewall rules that have been created when packets have
matched a configured firewall with the inspect-state keyword specified.
For more information on the inspect-state keyword, see
TTL
The number of seconds for the table entry to live. When this reaches 0, the entry is removed from
the table.
Hits
The number of times an IP packet has been matched against the firewall rule.
Direction
The direction of the IP packets that match the firewall rule.
Src IP Addr
The source IP address of the IP packets that match the firewall rule.
Src Port
The source TCP/UDP port of the IP packets that match the firewall rule.
Dest IP Addr
The destination IP address of the IP packets that match the firewall rule.
Dest Port
The destination TCP/UDP port of the IP packets that match the firewall rule.
Trans. Src IP Addr
If the firewall is configured to modify (such as NAT or NAPT) the source IP address of the IP
packets that match the firewall, this defines the new source IP address of the IP packets.
Trans. Src Port
If the firewall is configured to modify (such as NAPT) the source TCP/UDP port of the IP packets
that match the firewall, this defines the new source TCP/UDP port of the IP packets.
