• Verify that the IP addresses are properly configured.

For most applications, you should use the Barricade

ADSL Router’s DHCP function to dynamically assign

IP addresses to hosts on the attached LAN. However,

if you manually configure IP addresses on the LAN,

verify that the same network address (network

component of the IP address) and subnet mask are

used for both the Barricade ADSL Router and any

attached LAN devices.

• Be sure the device you want to ping (or from which

you are pinging) has been configured for TCP/IP.
