Masquerading-table

With IP masquerading, the IP addresses of computers in the local network are rendered invisible to external devices by means of a conversion of addresses and ports in the router. The dynamic masquerading table displays the IP addresses from the local network that the router is currently masking. The dynamic masquerading table can contain up to 2048 entries and has the following layout:

Intranet-addr. S-port Protocol Time
10.1.1.10 1234 TCP 10

The different columns have the following meaning:

O Intranet-addr.: IP address of the computer in the local network
O S-port: Source port for this entry
O Protocol: Protocol used (TCP/UDP/ICMP)
O Timeout: Time in seconds until the entry is removed from the table
