General FAQs

Q. How do I telnet to the NetGuardian SUI?
A. You must use Port 2002 to connect to the NetGuardian SUI. Configure your Telnet client to connect using TCP/
IP (not "Telnet," or any other port options). For connection information, enter the IP address of the NetGuardian
SUI and Port 2002. For example, to connect to the NetGuardian SUI using the standard Windows Telnet client,
click Start, click Run, and type "telnet <NetGuardian SUI IP address> 2002."
Q. How do I connect my NetGuardian SUI to the LAN?
A. To connect your NetGuardian SUI to your LAN, you need to configure the unit IP address, the subnet mask and
the default gateway. A sample configuration could look like this:
Unit Address: 192.168.1.100
subnet mask: 255.255.255.0
Default Gateway: 192.168.1.1
Save your changes by writing to NVRAM and reboot. Any change to the unit's IP configuration requires a reboot.
Q. When I connect to the NetGuardian SUI through the craft port on the front panel it either doesn't work
right or it doesn't work at all. What's going on?
A. Make sure your using the right COM port settings. Your COM port settings should read:
Bits per second: 9600 (9600 baud)
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None
Important! Flow control must be set to none. Flow control normally defaults to hardware in most terminal
programs, and this will not work correctly with the NetGuardian SUI.
Q. The LAN link LED is green on my NetGuardian SUI, but I can't poll it from my T/Mon.
A. Some routers will not forward packets to an IP address until the MAC address of the destination device has
been registered on the router's Address Resolution Protocol (ARP) table. Enter the IP address of your gateway
and your T/Mon system to the ARP table.
