Network Connection Problems
Cannot Ping the
Barricade from the
attached LAN, or the
router cannot Ping any
device on the attached
LAN
• Verify that IP addresses are properly configured. For
most applications, you should use the Barricade’s
DHCP function to dynamically assign IP addresses to
hosts on t he attac hed LAN. H owever, if you man ually
configure any 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 and attached LAN devices.
• Be sure the device you want to ping (or are pinging
from) has been configured for TCP/IP.
Management Problems
Cannot connect using a
Web browser
• Be sure the Barricade is configured with a valid IP
address, subnet mask and default gateway.
• Check that you have a valid network connection to the
Barricade and that the port you are using has not been
disabled.
• Check the network cabling between the management
station and the Barricade.
