Any
Accept remote requests from any IP address. Note that the
router cannot initial VPN connection when “Any” is
selected.
Encryption:
This item helps give your VPN connection added security.
There are two different type of encryption: “
DES”
or “
3DES”
.
DES uses 64-bit encryption key, and 3DES uses 128-bit
encryption key. You may choose either of them, but be aware
that both end of a VPN tunnel should use the same encryption
type. You may also choose not to enable encryption by
selecting “
Disable”
.
Authentication:
This item adds another level of security. There are two types of
authentication: “
MD5”
and “
SHA”
. You may choose either of
these but, as with encryption, both ends of the VPN tunnel
should use the
same authentication type
. You may also
choose not to use the authentication function by selecting
“
Disable”
.
Key Management:
In addition to use the same encryption type, both side of VPN
tunnel should also share the same encryption “
Key
”. This is
necessary for proper encryption security and allows the
encryption to function correctly. By using the
Key
Management
drop down list, you can choose two of two
methods to set the Encryption Key: “
key
”:
Auto (IKE)
or
Manual.
Auto (IKE):
With
Auto (IKE),
you must enter a series of characters in the
“
Pre-shared Key”
field. In the example shown in the figure
above, the word
Test
has been used. The program will
automatically generate the correct codes to be used in the
encryption and authentication basing on the word you entered.
You may use any combination of up to 23 alphanumeric
characters in this field. No special characters or spaces are
allowed.
By entering the number of seconds in the
Key Lifetime
field,
you may optionally select to have the key expire at the end of
the time you specify. Leave this field blank for the key to last
indefinitely.
