Chapter 5 Bridging

5.1 Overview

Chapter 5 and Chapter 6 describe how to configure the CT-510 in order to forward packets to LAN and ATM WAN interfaces. The CT-510 supports both bridging and routing modes. A bridge forwards packets on the basis of a physical level or Medium Access Control address (MAC). A router forwards packets on the basis of network-level addresses.

The CT-510 ADSL router can be configured to route IP or bridge other protocols between workstations on a Local Area Network (LAN) and up to 16 remote locations over an ATM Wide Area Network (WAN).

5.2 Static Bridging Configuration

This section describes the static bridging configurations. The user can add or delete a static MAC entry, or view the bridging parameters.

5.2.1 Add A Static MAC Entry

Step 1 Enter the MAIN/CONF/BRIDGING/STATIC/ADD menu.

Step 2 On the menu, input the MAC address and Port Map.

Note: Port Map

There are 17 characters used to specify the operating mode of 17 interfaces when the MAC address is processed in bridging mode. The first character represents the LAN interface (10000000000000000) and the last character represents the ATM16 interface (00000000000000001).

There are three operating modes: filter, forward, and dynamic, represented as 0, 1 and 2, respectively. The dynamic mode means that the operating mode of the MAC address in the interface follows the learnin result of the bridging function. For example, the port map of the MAC address is configured to be “10000000000000000". It means the MAC address will be forwarded to the LAN interface and filtered from all ATM interfaces. Similarly, 01000000000000000 means ATM interface 1.

Chapter 7 Network & Port Address Translation

7.1 Overview

Public IP addresses are registered and can be used within a public network, such as the Internet. Due to the limitation of IP version4 address space and the growth of the Internet, the public addresses are becoming more scarce. One solution to this problem is to use private addresses in the small LANs and to use Address Translation when accessing the CT-510 on a public network. Both Port Address Translation (PAT) and Network Address Translation (NAT) are supported by the CT-510.

1. If the PAT/NAT function is required, refer to Section 7.2 to enable the PAT/NAT function. Thus, all the hosts in the virtual LAN will transmit data by means of the PAT across the WAN IP addresses.

2. To set up a server that can be accessed by the Internet users, such as a SMTP server, Web server, and FTP server, refer to Section 7.3.

3. To further map the private IP addresses in the virtual LAN on to the specified global IP addresses, refer to Section 7.4.

Trouble Shooting

1 When the CT-510 is configured via the Console port using the VT-100

program, like HyperTerminal, the interface doesn’t respond properly. For example, the arrow keys cannot work when I need to move the cursor.

Solution1: We recommend you to upgrade your HyperTerminal to Edition 5 if

you are using Edition 4 or below.

Solution2: If you don’t want Solution 1, you can upgrade the firmware of CT-510 to Version 1.67 or above. For Version 1.67 and above, you can use other functional keys to replace the arrow keys. For example, the function of UP arrow key can be replaced by holding down CTRL-W. For descriptions of other arrow keys, please refer to Section 3.2.3.

2 Parameters are lost after restart

When you adjust or change the parameters, you should save the parameters

into the RAM by holding down Ctrl-S keys. This procedure only saves the parameters temporarily. Therefore, before you exit the system, you should save the confi menu and then reboot the system by entering the MAIN/REBOOT menu.

3 Console/Telnet/Web Passwords

According to default setting, the console password check function is

disabled; it is not required to enter passwords when you access console. But to access Telnet or Web, you will be requested to enter password. You can try the default passwords to log in.

4 Access denied

There are several conditions that will disable you to enter Console, Telnet or Web.
