Description
The table contains the following columns:
• Name
Shows the name of the VPN connection to which the settings relate.
• Default Ciphers
When enabled, a preset list is transferred to the VPN connection partner during
connection establishment. The list contains combinations of the three algorithms
(Encryption, Authentication, Key Derivation). To establish a VPN connection, the VPN
connection partner must support at least one of these combinations. Additional
information can be found in the section "IPsec VPN (Page 60)".
• Encryption
For phase 2, select the required encryption algorithm. Can only be selected if "Default
Ciphers" is disabled.
Additional information can be found in the section "IPsec VPN (Page 60)".
Note
The AES modes CCM and GCM contain separate mechanisms for authenticating data.
If you use a mode AES x CCM or AES x GCM for "Encryption", this will also be used
for
authentication. Then only the pseudo random function will be derived from the
"Authentication" parameter.
• Authentication
Specify the method for calculating the checksum. Can only be selected if "Default
Ciphers" is disabled.
The following methods are supported:
– MD5
– SHA1
– SHA512
– SHA256
– SHA384
