Confidential

Authentication

Select from “PSK”, “CA”, “XAUTH Init PSK” and “XAUTH Init CA” to be
used in IKE negotiation.
PSK: Pre-shared Key.
CA: Certification Authority.
XAUTH: Extended Authentication to AAA server.

PSK

Secrets

Enter the Pre-shared Key.

Null

Life Time @ IKE
Parameter

Set the lifetime in IKE negotiation.
Before an SA expires, IKE negotiates a new SA. As soon as the new SA is
set up, it takes effect immediately and the old one will be cleared
automatically when it expires.

SA Algorithm

Select from “DES_MD5_96”, “DES_SHA1_96”, “3DES_MD5_96”, “3DES_
SHA1_96”, “AES128_MD5_96”, “AES128_ SHA1_96”,
“AES192_MD5_96”, “AES192_ SHA1_96”, “AES256_MD5_96” and
“AES256_ SHA1_96” when you select “ESP” in “Protocol”;
Select from “AH_MD5_96” and “AH_ SHA1_96” when you select “AH”
in “Protocol”;
Note: Higher security means more complex implementation and lower
speed. DES is enough to meet general requirements. Use 3DES when
high confidentiality and security are required.

3DES_MD5_96

PFS Group

Select from “PFS_NULL”, “MODP768_1”, “MODP1024_2” and
“MODP1536_5”.
PFS_NULL: Disable PFS Group
MODP768_1: Uses the 768-bit Diffie-Hellman group.
MODP1024_2: Uses the 1024-bit Diffie-Hellman group.
MODP1536_5: Uses the 1536-bit Diffie-Hellman group.

PFS_NULL

Life Time @ SA
Parameter

Set the IPSec SA lifetime.
Note: When negotiating to set up IPSec SAs, IKE uses the smaller one
between the lifetime set locally and the lifetime proposed by the peer.

28800

DPD Time Interval

Set the interval after which DPD is triggered if no IPSec protected
packets is received from the peer.
DPD: Dead peer detection. DPD irregularly detects dead IKE peers.
When the local end sends an IPSec packet, DPD checks the time the last
IPSec packet was received from the peer. If the time exceeds the DPD
interval, it sends a DPD hello to the peer. If the local end receives no
DPD acknowledgment within the DPD packet retransmission interval, it
retransmits the DPD hello. If the local end still receives no DPD
acknowledgment after having made the maximum number of
retransmission attempts, it considers the peer already dead, and clears
the IKE SA and the IPSec SAs based on the IKE SA.

DPD Timeout

Set the timeout of DPD packets.
