Enable Firewall
If the firewall checkbox is selected, the Security submenu will display after the next
reboot. The user can then configure firewall features. If the firewall is not used,
this checkbox should not be selected so as to free up system resources.
Enable IGMP Multicast: Tick the checkbox to enable IGMP multicast (proxy).
IGMP (Internet Group Membership Protocol) is a protocol used by IP hosts to report
their multicast group memberships to any immediately neighboring multicast
routers.
Enable WAN Service:
Tick this item to enable the ATM service. Untick it to stop the ATM service.
Service Name: This is a user defined label.
Step 6: Click Next to display the following screen.
The Device Setup screen allows the user to configure the LAN interface IP address,
subnet mask, and DHCP server. To enable DHCP, select Enable DHCP server and
enter starting and ending IP addresses and the leased time.
Since the router occupies the first two IP addresses (192.168.1.1 and 192.168.1.2),
the default private address range provided by the ISP server in the router is
192.168.1.3 through 192.168.1.254.
If NAT is disabled, Enable DHCP Server Relay will be displayed as an option. To
enable it, select the Enable DHCP Server Relay radio button and enter the DHCP
Server IP Address. This allows the router to relay the DHCP packets from the remote
DHCP server. The remote DHCP server will provide the IP address.
