Network Enable this option to permit all the computers on the wireless network to simultaneously
share the connection to the Internet using a single ISP account. If you disable NAT,
address
client stations will not be able to access the Internet unless their IP addresses are valid
translation (NAT) on the Internet.
If the CN3000 is connected to a wired LAN, computers on the wired LAN can also take
advantage of NAT to share the Internet connection.
Limit NAT port range
When enabled, the CN3000 reserves a range of 50 TCP and 50 UDP ports for each
customer starting at port 5000, and maps all outgoing traffic for the customer within the
range.
Note: Enabling this feature only affects outgoing TCP/UDP traffic. Applications that set
an incoming port (Active FTP, for example) may choose a port that is outside of the
allocated port range.
Important: If you enable this feature you should not assign static NAT mappings in the
range 5000 to 10000.
