To specify IP addresses of local and remote subnets for this tunnel, click the ADD button (
the Tunneled Networks section.
If the IPsec tunnel operates over IKEv1 (1 is selected from the IKE version list in the The First
Phase section), you can create only one subnet.
If the IPsec tunnel operates over IKEv2 (2 is selected from the IKE version list in the The First
Phase section), you can create several subnets.
Move the switch to the right to enable the aggressive mode for mutual
authentication of the parties. Such a setting accelerates the connection
establishment, but reduces its security.
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
Select an encryption mode from the drop-down list.
Select an available encryption algorithm from the drop-down list.
Select a hashing mode from the drop-down list.
The length of the hash in bits.
Select a hashing algorithm from the drop-down list.
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.
The lifetime of the Second Phase keys in seconds. After the specified
period it is required to renegotiate the keys. The value specified in this
field should be greater than zero.
