20.3 The VPN Gateway Screen
The VPN Gateway summary screen displays the IPSec VPN gateway policies in the ZyWALL, as
well as the ZyWALL’s address, remote IPSec router’s address, and associated VPN connections for
each one. In addition, it also lets you activate and deactivate each VPN gateway. To access this
screen, click Configuration > VPN > Network > IPSec VPN > VPN Gateway. The following
screen appears.
Encryption Key This field is applicable when you select an Encryption Algorithm. Enter the encryption
key, which depends on the encryption algorithm.
DES - type a unique key 8-32 characters long
3DES - type a unique key 24-32 characters long
AES128 - type a unique key 16-32 characters long
AES192 - type a unique key 24-32 characters long
AES256 - type a unique key 32 characters long
You can use any alphanumeric characters or ,;|`~!@#$%^&*()_+\{}':./<>=-".
If you want to enter the key in hexadecimal, type “0x” at the beginning of the key. For
example, "0x0123456789ABCDEF" is in hexadecimal format; in “0123456789ABCDEF”
is in ASCII format. If you use hexadecimal, you must enter twice as many characters as
listed above.
The remote IPSec router must have the same encryption key.
The ZyWALL ignores any characters above the minimum number of characters required
by the algorithm. For example, if you enter 1234567890XYZ for a DES encryption key,
the ZyWALL only uses 12345678. The ZyWALL still stores the longer key.
Authentication
Key
Enter the authentication key. The length depends on the authentication algorithm.
MD5 - type a unique key 16-20 characters long
SHA1 - type a unique key 20 characters long
SHA256 - type a unique key 32 characters long
SHA512 - type a unique key 64 characters long
You can use any alphanumeric characters or ,;|`~!@#$%^&*()_+\{}':./<>=-". If you
want to enter the key in hexadecimal, type “0x” at the beginning of the key. For
example, "0x0123456789ABCDEF" is in hexadecimal format; in “0123456789ABCDEF”
is in ASCII format. If you use hexadecimal, you must enter twice as many characters as
listed above.
The remote IPSec router must have the same authentication key.
The ZyWALL ignores any characters above the minimum number of characters required
by the algorithm. For example, if you enter 12345678901234567890 for a MD5
authentication key, the ZyWALL only uses 1234567890123456. The ZyWALL still stores
the longer key.
