Internet Access Using P660 under Bridge mode

If the ISP limits some specific computers to access Internet, that means only the traffic to/from these computers will be
forwarded and the other will be filtered. In this case, we use P660 which works as an ADSL bridge modem to connect to the ISP. The ISP will generally give one Internet account and limit only one computer to access the Internet. See the figure below for this setup.

1. Ethernet connection

To connect your computer to the Prestige's LAN port, the computer must have an Ethernet adapter card installed. For connecting a single computer to the Prestige, we use a cross-over Ethernet cable.

2. TCP/IP configuration

Is most cases, the IP address of the computer is assigned by the ISP dynamically so you have to configure the computer as a DHCP client which obtains the IP from the ISP using DHCP protocol. The ISP may also provide the gateway, DNS via DHCP if they are available. Otherwise, please enter the static IP addresses for all that the ISP gives to you in the network TCP/IP settings. For Windows, we check the option 'Obtain an IP address automatically' in its TCP/IP setup, please see the example shown below.

The following procedure shows you how to configure your P660 as an ADSL Modem for bridging traffic. We will use SMT menu to guide you through the related menu. You can use console or Telnet for finishing these configurations.

1. Configure P660 as bridge mode in Menu 1 General Setup.

           Menu 1 - General Setup

           System Name= P660
           Contact Person's Name=
           Domain Name=
           Edit Dynamic DNS= No

           Route IP= No
           Bridge= Yes

2. Configure a LAN IP for the P660 and turn off DHCP Server in Menu 3.2-TCP/IP Ethernet Setup. We use in this case.  

           Menu 3.2 - TCP/IP and DHCP Setup

     DHCP Setup
           DHCP= None
           Client IP Pool Starting Address= N/A
           Size of Client IP Pool= N/A
           Primary DNS Server= N/A
           Secondary DNS Server= N/A
           Remote DHCP Server= N/A
      TCP/IP Setup:
           IP Address=
           IP Subnet Mask=
           RIP Direction= None
               Version= N/A
           Multicast= None
           IP Policies=
           Edit IP Alias= No

3. Configure for Internet setup in Menu 11-Remote Node Profile.  

                                                            Menu 11.1 - Remote Node Profile

                  Rem Node Name= Bridge                          Route= None
                  Active= Yes                                               Bridge= Yes

                  Encapsulation= RFC 1483                         Edit IP/Bridge= No
                  Multiplexing= LLC-based                          Edit ATM Options= No
                  Service Name= N/A                                   Edit Advance Options= No
                  Incoming:                                                    Telco Option:
                      Rem Login= N/A                                       Allocated Budget(min)= N/A
                      Rem Password= N/A                                 Period(hr)= N/A
                  Outgoing:                                                       Schedule Sets= N/A
                      My Login= N/A                                         Nailed-Up Connection= N/A
                      My Password= N/A                               Session Options:
                      Authen= N/A                                             Edit Filter Sets= No
                                                                                        Idle Timeout(sec)= N/A

Key Settings:  

Option Description
Encapsulation Select the correct Encapsulation type that your ISP supports. For exmaple, RFC 1483.
Multiplexing Select the correct Multiplexing type that your ISP supports. For exmaple, LLC.
Router/ Bridge Disable routing mode and enable bridge mode, Bridge = Yes. 

4. Configure ATM setting in Menu 11.6-Remote Node ATM Layer Options. In Menu 11.1, setup "Edit ATM Options= Yes" to enter Menu 11.6 sub-Menu.

Menu 11.6 - Remote Node ATM Layer Options

                                                           VPI #= 0
                                                           VCI #= 33
                                                           ATM QoS Type= CBR
                                                           Peak Cell Rate (PCR)= 0
                                                           Sustain Cell Rate (SCR)= 0
                                                           Maximum Burst Size (MBS)= 0

Key Settings: 

Option Description
VPI & VCI number  Specify a VPI (Virtual Path Identifier) and a VCI (Virtual Path Identifier) given to you by your ISP.
