Question: Does the broadband router support IPSEC?

Question: What type of firewall is the broadband router equipped with?

Answer:

A: The broadband router uses NAT and TCP/IP port inspections.

Question: What is NAT?

Answer:

Network Address Translation (NAT) translates multiple IP addresses on the private LAN to one public address that is sent out to the Internet. This provides security since the IP address of a computer on the LAN is not transmitted to the Internet. The user can have multiple private addresses behind the single address that was provided by the ISP.

Question: What is DMZ?

Answer:

DMZ stands for Demilitarized Zone. This feature allows one IP Address to be exposed to the Internet. DMZ allows only one computer to be exposed when multiple TCP/IP ports need to be open. If you want to use DMZ, you must set computer with a static IP.

Question: If DMZ is used, does the exposed user share the public IP with the broadband router?

Answer:

No, all specific requests are forwarded to the DMZ host.

Answer:

You should contact your ISP to get the full URL and then perform the following steps:

  2. Perform the ping command by clicking Windows Start and then Run. In the Run dialog box, Windows 95, 98, and Me users should type command. Windows 2000 and NT users should type cmd. All users should then enter the following command: ping xxx, where xxx is the complete URL for your ISP.
  3. After you get the IP Address, enter the IP address on the mail server option or the Internet browser.
