Port Forwarding table

To view the Port Forwarding table, go to Network Status > Port Forwarding Table. The Port
Forwarding Table page displays the Port Forwarding / NAT table. The router uses this table to keep
track of IP packets that have been modified via NAT or NAPT to be routed over a particular network.
When the router receives a response to a previously modified IP packet, it looks up the matching
entry in the Port Forwarding table to correctly modify the response IP packet.
Src IP Address
The source IP address of the modified IP packet.
Dest IP Address
The destination IP address of the modified IP packet.
IP Protocol
The IP protocol field of the modified IP packet.
Src Port
The source TCP/UDP port of the modified IP packet. For ICMP packets, this defines the ICMP
Echo identifier value.
NAPT Port
The new destination TCP/UDP of the modified IP packet. For ICMP packets, this defines the ICMP
Echo identifier value.
Dest Port
The original destination TCP/UDP port of the modified IP packet.
TTL
The time to live, in seconds, for the Port Forwarding entry. The router deletes any entries not in
use during this specified amount of time from the Port Forwarding table.
