Tools Required
• Category 5 - UTP crossover and/or straight-through (ST) cables, as required, for connection to existing network
• A PC with an internet browser (IE 5.5 or greater) for configuring the unit
In this document, the term "NetVanta 2000” means any router in the NetVanta 2000 series (e.g.,
NetVanta 2100, NetVanta 2300, etc). If a statement only applies to one particular router, the text
refers to the router individually.
Unpacking and Inspecting the System
Each NetVanta 2000 is shipped in its own cardboard shipping carton. Open each carton carefully and avoid deep
penetration into the carton with sharp objects.

2Connecting to the NetVanta
The NetVanta 2000 can be accessed and managed via the LAN interface using an Ethernet crossover cable
(provided with the NetVanta 2100). Alternately, the NetVanta 2000 may be accessed using a hub and two Ether-
net cables (one for the PC and one for the NetVanta). Using a PC with an installed browser (Internet Explorer
5.5 for optimal viewing), the NetVanta can be configured using the web GUI. WAN connections are made in the
same manner and with the same cabling considerations as LAN connections.
3Configuring the System
1. Connect the NetVanta 2000 LAN interface to the PC using the appropriate Ethernet cable.
2. Supply power to the PC and the NetVanta 2000 and begin the operating system boot up process. During
boot up, the PC obtains an IP address from the NetVanta 2000 DHCP server. Alternately, you could manu-
ally change your IP address to 10.10.10.10/24. Refer to your specific operating system’s documentation for
details on that process.
3. Open your installed browser, and enter 10.10.10.1 in the URL field. The NetVanta 2000 login screen
appears.
4. Enter admin as the username, enter your admin password (if set), and click the Login button. When con-
necting to the NetVanta for the first time, there is no set password.
5. After logging in to the NetVanta 2000, the welcome screen appears.
For security purposes, it is important to set up an admin password immediately. Refer to the
NetVanta 2000 System Manual (PN 61200361L1-1) for details.

If you wish to obtain a new IP address from the NetVanta 2000 DHCP server, you must release and renew your sys-
tem’s captured IP addresses. Refer to your specific operating system’s documentation for details on that process if it
differs from the procedure provided below.
1. Click Start on the task bar.
2. Choose Run; then type WINIPCFG in the text field.
3. Click Release to reset all IP parameters.
4. Click Renew to obtain new IP parameters.

Configuring the LAN and WAN IP Parameters
4
The NetVanta 2000 comes factory-programmed with a LAN IP address of 10.10.10.1 (24-bit subnet mask) and no
pre-programmed WAN IP address. The procedures outlined in this step include changing both the LAN and WAN
IP parameters.
The NetVanta 2000 supports three types of WAN IP addresses: Dynamic, Static, and PPPoE (PPP overEthernet).
The IP parameters for your WAN interface must be supplied by your Internet Service Provider (ISP). If your ISP is
performing DHCP for IP address assignment (which is common in cable modems), configure the NetVanta 2000
for Dynamic addressing. Use PPPoE when your ISP has supplied you with the configuration parameters for
PPPoE (including a username and password).
Changing the LAN IP parameters through the LAN interface results in a loss of management connectivity.
Follow the correct procedure for your operating system to change the IP address of the managing PC to match
the new NetVanta LAN IP parameters.
1. Select CONFIG.
2. Select Network Interface.
3. Enter the assigned LAN IP address and associated Subnet Mask.
4. Enable the Static radio button for static addressing.
Your WAN IP address scheme is supplied by your provider. Static addressing is used above
only as an example.
5. Enter the assigned WAN IP address and associated Subnet Mask.
The WAN IP parameters are set by the service provider. Contact your ISP before configuring
the unit.
6. Click Submit to register the changes.

4b Configuring the DHCP Server IP Parameters - Optional
The NetVanta 2000 automatically populates the DHCP IP Address Range 1 with ten addresses based on your
assigned LAN network address.
1. Select CONFIG.
2. Select DHCP server.
3. Enter an IP address range that is on the same subnet as the assigned LAN IP address of the unit.
4. Enter the assigned LAN IP address of the unit.
5. Click Submit to register the changes.

4. Select WAN to associate this default route with the WAN interface.
5. Select Yes to configure this as the default.
6. Enter all zeros.
7. Enter the next hop IP address for the Gateway IP Address.
The Gateway IP Address is supplied by your provider.
8. Click Add Route to submit this route to the route table.

Defining a VPN Policy
IKE Policy Configuration

1. Select POLICIES.
2. Select VPN.
3. Select IKE.
4. Click the Add button.
This example assumes the NetVanta 2300 is already similarly configured for a VPN connection
to this NetVanta 2100.

IKE Policy Configuration (continued)
1. Enter an alphanumeric string (spaces are not valid characters) used to identify this policy.
2. Select BOTH DIRECTIONS to allow IKE to be initiated by either the local or remote NetVanta.
3. Select MAINMODE as the Exchange Type.
If both sides do not have permanent IP addresses, see the Aggressive Mode tech note on
www.adtran.com.
4. Use the unique Fully Qualified Domain Name (FQDN) for the local NetVanta 2000 and enter the identifi-
cation data (these need not be registered names).
5. Use the unique FQDN for the remote users and enter the identification data (these need not be registered
names).
6. Enter the local NetVanta 2000's assigned WAN IP address.
7. Enter the remote NetVanta 2000's assigned WAN IP address.
8. Select 3DES to invoke Triple DES encryption.
9. Select SHA to use the secure hash authentication algorithm #1.
10. Select Pre-SharedKey and enter the key as a 12-character (minimum) alphanumeric string (spaces are
not valid characters). This key MUST be the same for both the local and remote units.
11. Set the Life time of key to 86400 seconds (this is the ADTRAN suggested value).
When determining the appropriate value for your application, typical usage contains a 3:1 ratio
between the IKE and IPSec key lifetime values. This ratio provides for key negotiation overhead.
12. Select Group 2 to invoke Diffie-Hellman Group 2.
13. Click SUBMIT to register the changes.

1. Enter an alphanumeric string (spaces are not valid characters) to identify this policy (this is usually the
same as the IKE name).
2. Select ENABLE to configure this as an active policy.
3. Select OTHER and enter the local NetVanta 2000's assigned LAN network address (e.g., 10.10.20.0) and
associated subnet mask.
4. Select OTHER and enter the remote NetVanta 2000's assigned LAN network address (e.g., 10.10.10.0)
and associated subnet mask.
5. Select ANY (for both the Source Port and Destination Port) to apply this policy to all data ports.
6. Select ALL to apply this policy to all data protocols.
7. Enter the remote NetVanta 2000's assigned WAN IP address.
If the remote NetVanta 2000 is configured for dynamic addressing on the WAN interface, enter
0.0.0.0 here.
8. Select NONE.
9. Select ESP WITH AUTH.
10. Select SHA1 to invoke secure hash algorithm #1.
11. Select 3DES to use Triple-DES encryption algorithm.
12. Set the key lifetime value to 28800 seconds (this is the ADTRAN suggested value).
When determining the value for your application, typical usage contains a 3:1 ratio between the
IKE and IPSec key lifetime values. This ratio provides minimal key negotiation overhead.
13. Select LAST TRANSFORM for both Security Protocol settings.
