General FAQs

Q. How do I Telnet to the NetGuardian?
A. You must use Port 2002 to connect to the NetGuardian. Configure your Telnet client to connect
using TCP/IP (not Telnet, or any other port options). For connection information, enter the IP

standard Windows Telnet client, click Start, click Run, and type Telnet <NetGuardian IP address>
