POSSIBLE PITFALL WITH ROUTERS, GATEWAYS, AND SWITCHES
Anytime computers communicate through routers, gateways, and switches, they may be allowed or denied the connection.
Network interface devices can be configured to block specific outgoing requests, as well as incoming requests, based on the IP
Address and/or port. This is one of the security mechanisms of a router. This also happens when broadcast messages are sent
and received.
To view the path an IP Address takes to retrieve information , do the following:
1.
From the Start Menu, open a Command Prompt screen.
2.
At the prompt, type tracert and type the url or IP Address you want to trace.
3.
Press Enter .
The details of the tracer route are displayed .
NOTE: The message request timed out appears if the IP Address port in or out is denied to the incoming or outgoing
message.
4.
When you are finished, type exit to close the Command Prompt window.
