Description
IKE version
IKE (
Internet Key Exchange
) is a protocol of keys exchange between
two hosts of VPN connections. Select a version of the protocol from
the drop-down list.
The Second Phase
Second phase
encryption algorithm
Select an available encryption algorithm from the drop-down list.
Encryption mode
Select an encryption mode from the drop-down list.

Enable PFS
Move the switch to the right to enable the PFS option (
Perfect
Forward Secrecy
). If the switch is moved to the right, a new
encryption key exchange will be used for the Second Phase. This
option enhances the security level of data transfer, but increases the
load on DIR-822.

A Diffie-Hellman key group for the Second Phase. Select a value from
the drop-down list. The drop-down list is available if the
Enable PFS
switch is moved to the right.
IPsec-SA lifetime

period it is required to renegotiate the keys. The value specified in this
field should be greater than zero.
To specify IP addresses of local and remote subnets for this tunnel, click the

Phase
section), you can create only one subnet.
If the IPsec tunnel operates over IKEv2 (
2
is selected from the
