+add pat entry <public_port_#>

+add pat entry default

Creates static entries in the Network Address Translation table.
Each IP packet received from the Internet interface is examined. If the destination
address is the public address of the interface, the router searches the Network
Address Translation table for a match. If the address is found, the destination
address is replaced with the associated private address and port number. The
packet is then forwarded to the IP routing process. If no match is found and a
Default Private Receiver is defined, the packet is forwarded to the specified
device.
Note: Static entries are mapped by port number and therefore multiple
protocols using the same port number are routed to the mapped entry.
Example 1
In this example, IP packets received with a destination port number of 123 are
translated to port 234 with a destination private IP address of 192.168.168.120.
BayStack> add pat entry 123
Enter Private IP Address: 192.168.168.120
Enter Private Port Number: 234
Example 2
In this example, IP packets received with a destination port number not found in
the Network Address Translation table are translated to a destination private IP
address of 192.168.168.121.
BayStack> add pat entry default
Enter Private IP Address: 192.168.168.121
delete arp <target_IPaddr>
Deletes the specified ARP table entry.
