•
Verify that the IP addresses are properly configured.
For most applications, you should use the Barricade’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 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.
