Chapter 4 Using the Command-Line Interface for Quick Configuration

Configuring Ethernet Interfaces

This section describes how to configure the VPN Concentrator Ethernet interfaces.

• Ethernet 1 (Private) is the interface to your private network (internal LAN).

• Ethernet 2 (Public) is the interface to the public network.

• Ethernet 3 (External), if present, is the interface to an additional LAN.

For the VPN Concentrator to become fully operational, you must configure the two interfaces you

physically connected to your network in the “Connecting Network Cables” section on page 2-9.

To configure the VPN Concentrator Ethernet Interfaces, follow these steps:

Step 1 The system prompts you to configure the VPN Concentrator interfaces.

Model 3005 Menu

1) Modify Ethernet 1 IP Address (Private)

2) Modify Ethernet 2 IP Address (Public)

3) Save changes to Config file

4) Continue

5) Exit

Quick -> _

Model 3015–3080 Menu

1) Modify Ethernet 1 IP Address (Private)

2) Modify Ethernet 2 IP Address (Public)

3) Modify Ethernet 3 IP Address (External)

4) Save changes to Config file

5) Continue

6) Exit

Quick -> _

You entered values for Ethernet 1 under “Using the Console” section on page 2-15. You can change them

now; to do so, enter

1 at the cursor. To configure another interface, enter its number at the cursor.

Step 2 We assume you enter 2 to configure Ethernet 2. The CLI displays a table with the current IP addresses

and subnet masks for all three Ethernet interfaces.

This table shows current IP addresses.

Interface IP Address/Subnet Mask MAC Address

-----------------------------------------------------------------

Ethernet 1 - Private | 10.10.4.6/255.255.0.0 | 00.10.5A.1F.4F.07

Ethernet 2 - Public | 0.0.0.0/0.0.0.0 |

Ethernet 3 - External | 0.0.0.0/0.0.0.0 |

-----------------------------------------------------------------

> Enter IP Address for Ethernet 2 (Public)

Quick -> [ 0.0.0.0 ] _

At the cursor, enter the IP address for the VPN Concentrator Ethernet 2 (Public) interface, using dotted

decimal notation; for example, 192.168.12.34. Be sure no other device is using this address on the

network. (Note that Ethernet 3 appears on models 3015-3080 only.)
