displays the IP Address,
Host Name and MAC
Address of each client

the MAC address linked
so that the IP address will
always be assigned as it is
on this screen.

Application features that provide control over the TCP/ UDP port
openings in the Modem-Router’s firewall. This section can be used to

public IP addresses to be
shared by multiple internal
users. You can enable
or disable NAT here.
