Diagnostics Web Page
This page verifies you have IP connectivity from your gateway to other IP addresses on the LAN
side, such as when you want to confirm you have successfully configured one of your PCs for
TCP/IP operation.
When you ping an Internet device, you send a packet to its TCP/IP stack, and it sends one back to
yours. Enter the IP address you want to ping, then click Start Test. Wait a few seconds, then click
your web browser’s refresh button. Success reported in the Results box means IP connectivity is
working from your CM TCP/IP stack to the target’s stack.
Note: Firewalls may cause pings to fail but still provide you TCP/IP access to selected devices
behind them. Keep this in mind when pinging a device that may be behind a firewall. Ping is most
useful to verify connectivity with PCs you know have no firewall, such as your own PCs on your
LAN side.
