| IP Version |
Select an IP version (IPv4 or IPv6) of the current Non SD-WAN Destination from the drop-down menu. |
| Primary VPN Gateway |
| Public IP |
Enter a valid IPv4 or IPv6 address. This field is mandatory. |
| View advanced settings for IKE Proposal: Expand this option to view the following fields. |
| Encryption |
Select the AES algorithm key size from the drop-down list, to encrypt data. The available options are AES 128, AES 256, AES 128 GCM, AES 256 GCM, and Auto. The default value is AES 128. |
| DH Group |
Select the Diffie-Hellman (DH) Group algorithm from the drop-down list. This is used for generating keying material. The DH Group sets the strength of the algorithm in bits. The supported DH Groups are 2, 5, 14, 15, 16, 19, 20, and 21. The default value is 14. |
| Hash |
Select one of the following supported Secure Hash Algorithm (SHA) functions from the drop-down list:
The default value is SHA 256. |
| IKE SA Lifetime(min) |
Enter the time when Internet Key Exchange (IKE) rekeying is initiated for Edges. The minimum IKE lifetime is 10 minutes and maximum is 1440 minutes. The default value is 1440 minutes.
Note: Rekeying must be initiated before 75-80 % of lifetime expires.
|
| DPD Timeout(sec) |
Enter the DPD timeout value. The DPD timeout value will be added to the internal DPD timer, as described below. Wait for a response from the DPD message before considering the peer to be dead (Dead Peer Detection).
Prior to the 5.1.0 release, the default value is 20 seconds. For the 5.1.0 release and later, see the list below for the default value.
- Library Name: Quicksec
- Probe Interval: Exponential (0.5 sec, 1 sec, 2 sec, 4 sec, 8 sec, 16 sec)
- Default Minimum DPD Interval: 47.5sec (Quicksec waits for 16 seconds after the last retry. Therefore, 0.5+1+2+4+8+16+16 = 47.5).
- Default Minimum DPD interval + DPD Timeout(sec): 67.5 sec
Note: For the 5.1.0 release and later, you cannot deactivate DPD by configuring the DPD timeout timer to 0 seconds. The DPD timeout value in seconds gets added into the default minimum value of 47.5 seconds.

| Encryption |
Select the AES algorithm key size from the drop-down list, to encrypt data. The available options are None, AES 128, and AES 256. The default value is AES 128. |
| PFS |
Select the Perfect Forward Secrecy (PFS) level for additional security. The supported PFS levels are 2, 5, 14, 15, 16, 19, 20, and 21. The default value is 14. |
| Hash |
Select one of the following supported Secure Hash Algorithm (SHA) functions from the drop-down list:
The default value is SHA 256. |
| IPsec SA Lifetime(min) |
Enter the time when Internet Security Protocol (IPsec) rekeying is initiated for Edges. The minimum IPsec lifetime is 3 minutes and maximum is 480 minutes. The default value is 480 minutes.
Note: Rekeying must be initiated before 75-80 % of lifetime expires.
