TECHNICAL SUPPORT NOTE
Using the GUI to Configure a NetVanta 1224R/STR for Internet Access
using an Ethernet Port (Cable or DSL modem)
Featuring ADTRAN OS and the Web GUI
_____________________________________________________________________________________
Introduction
This Technical Support Note shows how to configure the NetVanta 1224R/STR for an Internet
connection using an ethernet port. In this scenario, you will usually have a separate cable or
DSL modem that will handle the

Step 2 – Setting up the Private VLAN Interface Click the “VLANs” link to setup the IP addresses for the unit. In the following diagrams, we will change the default IP address to 192.168.1.254. Note: When you submit the default IP address change, you will need to change your workstation IP address to match up with the new subnet and reconnect to the NetVanta using the new IP address. For example, after making the IP address change, set your workstation IP address to 192.168.1.1.

Change the IP address to 192.168.1.254. After changing the default VLAN interface IP address, be sure to change your workstation IP address to match this network. For example, you could use 192.168.1.1 as your workstation IP address with a default gateway of 192.168.1.254.

Step 3 – Add a New VLAN for the Public Subnet (Port) The public VLAN will be configured in one of three different modes, (A) IP Routing with a Static IP, (B) IP Routing using DHCP, or (C) PPPoE. DHCP is normally used when connected to a cable modem and PPPoE is often used when connected to a DSL modem set in pass-through or bridge mode. The following pages will show an example of each different scenario. We will use VLAN 100 for the public VLAN and 100.100.100.2/30 as the public IP add

(Option A) – IP Routing with a Static IP Configuration. The IP address 100.100.100.2 is used as an example. The IP address information should have been provided to you by your Internet Service Provider (ISP).

(Option B) – IP Routing Using DHCP. This is a typical cable modem setup.

(Option C) – PPPoE (ADSL modem set to pass-through mode) Set the Interface Mode to PPPoE and click “Apply”. Clicking “Apply” will open a new page to set PPPoE specific settings.

(Option C) – PPPoE specific settings A username and password are required for PPPoE. Service Name and AC Name are rarely used but should be entered if provided by the ISP. Peer Authentication type should almost always be set to “None”. Also, PPPoE should be set for “Negotiated” IP address unless the ISP has specified a static IP address. Whenever a static IP address is used, you will need to complete the optional step 4, which shows how to configure a static default route.

Step 4 – Adding a Default Route when using a Static IP Address This step is not required when learning a default route dynamically as in step 3 (option B) when we used DHCP. You need to add a static default route when using IP Routing with a static IP address or PPPoE with a static IP address. Click the “Route Table” link and then add a static default route by specifying the destination network and subnet mask as 0.0.0.0. In our example, the static IP address assigned to us by our ISP

Step 5 – Assign an Ethernet Port to be a member of the Public VLAN In the example below, we are setting the first Ethernet port as a member of VLAN 100 and setting it to “edgeport” mode to allow this port to come up immediately. This port should be plugged into your Internet connection. Make sure your workstation is not plugged into this port and remember to click the “Apply” button. Also, it is probably a good idea after making this change to click the “Save” button to save the conf

Step 6-1. The first wizard page is just a warning that this will overwrite any previous firewall settings. Step 6-2. Select the public VLAN interface. In our example, this is VLAN 100.

Step 6-3. This step will allow you to setup some basic port forwarding. Port forwarding can be done at a later date by adding policies to the “Public” Security Zone. Step 6-4. The final step is to confirm that the default VLAN 1 will share the IP address applied to the public VLAN 100.

Step 7 – Save Your Changes The basic configuration should be complete after using the Firewall Wizard. Be sure to click “Save” after you make any configuration changes. This will ensure that the configuration will be maintained in the unit by storing it in the NVRAM. Step 8 – Consult Additional Documentation Additional Documentation is available at www.adtran.com using the “Service/Support” link or doing a search for “ADTRAN OS Web GUI”.
