row. You must confirm your changes by clicking "OK". If you

change your mind before clicking "OK", click "Cancel" to reverse

your changes.

Click "Move" to directly specify a new location for the selected

policy.

Enable/Disable

Use this to toggle the On/Off state of the selected policy.

Copy

If you wish to create a policy which is similar to an existing policy,

select the policy and click the "Copy" button.

Remember that the new policy must have a different name, and there can

only be one active (enabled) policy for each remote VPN endpoint.

Delete

To delete an exiting policy, select it and click the "Delete" button.

View Log

Clicking the "View Log" button will open a new window and display the

VPN log.

Figure 49: VPN Wizard - General

Policy Name

Enter a suitable name. This name is not supplied to the remote VPN. It is

used only to help you manage the policies.

Enable Policy

Enable or disable the policy as required. For each remote VPN, only 1

policy can be enabled at any time.

Remote VPN

Endpoint

The Internet IP address of the remote VPN endpoint (Gateway or client).

•

Dynamic

. Select this if the Internet IP address is unknown. In this

case, only incoming connections are possible.

•

Fixed

. Select this if the remote endpoint has a fixed Internet IP

address.

Keys

Select

Manually assigned

or

IKE

(Internet Key Exchange) as required.

If you are setting up both endpoints, using IKE is recommended.

Figure 50: VPN Wizard - Traffic Selector

•

For outgoing VPN connections, these settings determine which traffic will cause a VPN

tunnel to be created, and which traffic will be sent through the tunnel.

•

For incoming VPN connections, these settings determine which systems on your local

LAN will be available to the remote endpoint.

•

The 2 VPN endpoints MUST use different address ranges.

If the addresses were in the same range, traffic intended for the remote VPN would be

considered local LAN traffic. So it would not be forwarded to the Gateway.

Type

•

Any

- no additional data is required. Any IP address is accept-

able.

•

For outgoing connections, this allows any PC on the LAN to

use the VPN tunnel.

•

For incoming connections, this allows an PC using the re-

mote endpoint to access any PC on your LAN.

•

Single address

- enter an IP address in the "Start IP address"

field.

•

Range address

- enter the starting IP address in the "Start IP

address" field, and the finish IP address in the "Finish IP ad-

dress" field.

•

Subnet address

- enter the desired IP address in the "Start IP

address" field, and the network mask in the "Subnet Mask" field.

The remote VPN must have these IP addresses entered as it's "Re-

mote" addresses.

Manual Key Exchange

VPN

These settings must match the remote VPN. Note that you cannot use both AH and ESP.

AH Authentication

AH (Authentication Header) specifies the authentication protocol

for the VPN header, if used. (AH is often NOT used)

If AH is not enabled, the following settings can be ignored.

Keys

•

The "in" key here must match the "out" key on the remote

VPN, and the "out" key here must match the "in" key on the

remote VPN.

•

Keys can be in ASCII or Hex (0..9 A..F)

•

For MD5, the keys should be 32 hex/16 ASCII characters.

•

For SHA-1, the keys should be 40 hex/20 ASCII characters.

SPI

•

Each SPI (Security Parameter Index) must be unique.

•

The "in" SPI here must match the "out" SPI on the remote

VPN, and the "out" SPI here must match the "in" SPI on the

remote VPN.

•

Each SPI should be at least 3 characters.

ESP Encryption

ESP (Encapsulating Security Payload) provides security for the

payload (data) sent through the VPN tunnel. Generally, you will

want to enable both Encryption and Authentication.

•

The "3DES" algorithm provides greater security than "DES",

but is slower.

•

The "in" key here must match the "out" key on the remote

VPN, and the "out" key here must match the "in" key on the

remote VPN.

ESP Authentication

Generally, you should enable ESP Authentication. There is little

difference between the available algorithms. Just ensure each

endpoint use the same setting.

•

The "in" key here must match the "out" key on the remote

VPN, and the "out" key here must match the "in" key on the

remote VPN.

•

Keys can be in ASCII or Hex (0..9 A..F)

•

For MD5, the keys should be 32 hex/16 ASCII characters.

•

For SHA-1, the keys should be 40 hex/20 ASCII characters.

ESP SPI

This is required if either ESP Encryption or ESP Authentica-

tion is enabled.

•

Each SPI (Security Parameter Index) must be unique.

•

The "in" SPI here must match the "out" SPI on the remote

VPN, and the "out" SPI here must match the "in" SPI on the

remote VPN.

•

Each SPI should be at least 3 characters.

For Manual Key Exchange, configuration is now complete.

•

Click "Next" to view the final screen.

•

On the final screen, click "Finish" to save your settings, then "Close" to exit the Wizard.
