Lucent Technologies 5800 Series Manual De Usuario

To provide secure connections across the Internet, consider purchasing the 

Virtual Private Network (VPN) software option.  Additional information on NAT, 

Firewall, and Secure VPN can be found in the CLI Reference Manual.

Yes, but you need to configure your router appropriately using the NAT Setting 

screen or the Command Line Interface (CLI).  By entering a remote system 

or addServer command, you can add FTP, Mail, NetMeeting or Web servers 

to your LAN.  These can then be accessed from another LAN or the Internet 

while NAT is enabled.

MER (MAC Encapsulated Routing) allows your router to perform routing on the 

LAN side and bridging on the WAN side.  MER is needed only when your 

Network Service Provider doesn’t support IP routing.  MER adds NAT 

functionality, thereby providing greater security and more IP addresses for your 

LAN than what is provided by your NSP.

If you do not get a response, try pinging the IP address.  If you get a response to 

pinging, then your Domain Name Service (DNS) is probably failing.  You should 

contact your NSP for DNS assistance.  If you do not get a response, then try 

pinging the WAN Gateway address (of your NSP) to confirm that your router can 

connect with the NSP.

If pinging fails, check the router’s lights.  The Link lights on the router front 

should be green.  Also check your cable connections.  If everything appears 

correct, check your IP configuration and ensure that the gateway and LAN IP 

addresses match.

You need a special DB9 to DB25 connector, available from the Efficient 

Networks web site at the following address: http://www.efficient.com

Yes, you can use a non-V.90 modem with your router for dial backup.  Be sure to 

use the correct initialization string for your modem (consult your modem 

documentation).
