Configuring Mulitple Static IP Addresses 69 If you did not receive a subnet mask from your ISP, but were provided with a number of addresses has been, you can look up the associated subnet mask in the table below. Because this information may have been identified in a number of different ways, it has been presented here in a number of different ways. Step 2: Allocate Public IP Addresses to the LAN Clients This step requires that all network devices that you wish to configure with a broadband IP...

Configuring Mulitple Static IP Addresses 70 For devices using the Public Network addresses, simply configure the device to use the IP address (subnet mask and default gateway) as assigned by the ISP . The gateway will automatically detect the usage of a broadband IP address on the LAN network and correctly ro ute the return traffic to the appropriate LAN device. Once a broadband IP address has been detected by the gateway as being statically coded on the device, its entr y in the Address Allo...

Configuring Mulitple Static IP Addresses 71 Sample Configuration In the sample network below, the customer has subscribed to ser vice with an 8 IP address subnet (i.e., 5 usable broadband IP addresses). The customer wants to host dedicated VPN and web servers in addition to having PCs with private IP addresses. The subnet assigned to the customer is 208.35.230.192/29. The sample network is shown in Figure *. Figure *. Sample Network Following are the steps required to config ure the gateway for...

Configuring Mulitple Static IP Addresses 72 First, configure the gateway to suppor t “Public Network” static IP addressing using the ser vice provider assigned IP addresses of 208.35.206.198 for the gateway and a subnet mask of 255.255.255.248 as shown in Figure xxx. Click SAVE to ensure the changes are saved. Figure xx Second, assign static IP addresses to the Network Ser vers from the available. This can be done by hard coding these on the network interface for t hese ser vers or via the gateway...

Configuring Mulitple Static IP Addresses 73 Edit the addresses assigned to each device as shown below. Assign an available static IP address to each ser ver, selecting the “DHCP Fixed” option from the lis t box next to each ser ver name. For this example, select the following options: Click SAVE after making your selections in order to ensure the addresses are properly assigned. After this step, restar t each server so that it is issued the desired static IP address. Finally, configure the gateway...

Configuring Mulitple Static IP Addresses 74 In the case of the Web Ser ver, the “hosted application” feature of the 3700HGV-B will be used. This feature provides a quick and easy way to allow specific types of unsolicited traffic through the 3700HGV-B firewall. For the web ser ver, this includes traffic on TCP port 80 (http). Select the computer to which you would like to have a ll data sent. In this example, the computer selected is VPNSRV. Select Allow all applications and click DONE. Doing so...

Configuring Mulitple Static IP Addresses 75 To allow all traffic for the web ser ver, configure the gateway to allow the specific type of the associated inbound por ts to flow to the ser ver. In this example, the computer WEBSRV is selected as the destination for the web ser ver traffic. Select the Allow individual application(s) option. Select the appropriate application fr om the application list, click the ADD buttton, and then click the DONE button. In this example, the application type is “Web...

76 LEDs LED overview The 2Wire Gateway has numerous indicator lights that can be used to diagnose installation and connection problems. The following table describes how to interpret the indicator lights. Power LED Solid green The gateway is powered on. Off The gateway is not receiving power. Flashing red Power-On Self-Tes t (POST) is in progress. Solid red POST failure (not bootable), or a gateway malfunction occurred. Local Ethernet, Wireless, USB - PC, or MoCA LEDs Solid green The device has...

LEDs 77 Service LED Solid green IP connected (The residential gateway has a WAN IP address from IPCP or DHCP and the broadband connection is up, or a static IP address is configured, PPP negotiation has successfully completed - if used - and the broadband connection is up). Off The gateway is not receiving power. The gateway is in bridged mode. Broadband connection is not established. Flashing green Attempting to connect via PPP . Attempting to establish IEEE 802.1X authentication. Attempting to...
