Encapsulation

Protocol-

There are two protocols that can be selected: ESP and AH.

Encryption

Algorithm-

There are two algorithms that can be selected: 3DES and DES.

Authentication

Algorithm-

There are two algorithms that can be selected: SHA1 and MD5.

Encryption Key-

For DES, the encryption key is 8 bytes (16 Char.). For 3DES,

the encryption key is

24 bytes (48 Char.).

Authentication Key-

For MD5, the authentication algorithm is16 bytes (32 Char.).

For SHA1, the authentication algorithm is 20 bytes.(40 Char.).

Life Time-

Enter in the life time value.

Life Time Unit-

There are two units that can be selected: Second and KB.

Home >VPN Settings > Dynamic VPN Tunnel

Using the Configuration Menu

Local Subnet-

The subnet of the VPN gateway’s local network. It can be a

host, a partial subnet or a whole subnet.

Local Netmask-

The netmask of the VPN gateway’s local network.

Aggressive Mode-

Enabling this mode will accelerate establishing the tunnel,

but the device will have less security.

Tunnel Name-

Current tunnel name.

This feature works with a VPN software client so the DI-804HV

does not need to know the IP address of the remote clients.

Dynamic VPN-

There are three parts that are necessary to setup the

configuration of IKE for the dedicated tunnel: basic setup, IKE

proposal setup, and IPSec proposal setup. Basic setup

includes the setting of following items: local subnet, local

netmask, remote subnet, remote netmask, remote gateway,

and pre-shared key. The tunnel name is derived from previous

page of VPN setting. IKE proposal setup includes the setting

of a set of frequent-used IKE proposals and selecting from the

set of IKE proposals.

Preshared Key-

The first key that supports IKE mechanism of both VPN

gateways for negotiating further security keys. The pre-

shared key must be the same for both endpoint gateways.

IKE Proposal index-

Click the button to setup a set of frequent-used IKE

proposals and select from the set of IKE proposals for the

dedicated tunnel.

IPSec Proposal

index-

Click the button to setup a set of frequent-used IPSec

proposals and select from the set of IKE proposals for the

dedicated tunnel.

IKE Proposal index-

Proposal Name-

DH Group-

Encrypt algorithm-

Auth algorithm-

A list of selected proposal indexes from the IKE proposal pool

listed below.

There are three groups can be selected: group 1 (MODP768),

group 2 (MODP1024), group 5 (MODP1536).

There are two algorithms that can be selected: 3DES and

DES.

It indicates which IKE proposal to be focused. First char of

the name with 0x00 value stands for the IKE proposal is not

available.

There are two algorithms that can be selected: SHA1 and

MD5.

Life Time Unit-

There are two units that can be selected: second and KB.

Proposal ID-

The identifier of IKE proposal can be chosen for adding

corresponding proposal to the dedicated tunnel.

Add

to-

Click it to add the chosen proposal indicated by proposal ID

to IKE Proposal index list.
