Netgear FVS318Gv2 – ProSAFE VPN Firewall Series Reference Manual

Key-Out

The encryption key for the outbound policy. The length of the key depends on 
the selected encryption algorithm:

3DES.  Enter  24  characters.

None.  Key  does  not  apply.

DES.  Enter  8  characters.

AES-128.  Enter  16  characters.

AES-192.  Enter  24  characters.

AES-256.  Enter  32  characters.

SPI-Outgoing

The security parameter index (SPI) for the outbound policy. Enter a hexadecimal 
value between three and eight characters (for example, 0x1234).

Integrity Algorithm

From the list, select the algorithm to be used in the VPN header for the 
authentication process:

SHA-1. Hash  algorithm that  produces  a  160-bit digest.  This  is  the default 
setting.

MD5.  Hash  algorithm  that  produces  a  128-bit  digest.

Key-In

The integrity key for the inbound policy. The length of the key depends on the 
selected integrity algorithm:

MD5.  Enter  16  characters.

SHA-1.  Enter  20  characters.

Key-Out

The integrity key for the outbound policy. The length of the key depends on the 
selected integrity algorithm:

MD5.  Enter  16  characters.

SHA-1.  Enter  20  characters.

These fields apply only when you select Auto Policy as the policy type.

SA Lifetime

The lifetime of the security association (SA) is the period or the amount of 
transmitted data after which the SA becomes invalid and must be renegotiated. 
From the list, select how the SA lifetime is specified:

Seconds. In the SA Lifetime field, enter a period in seconds. The minimum 
value  is  300  seconds.  The  default  setting  is  3600  seconds.

KBytes. In the SA Lifetime field, enter a number of kilobytes. The minimum 
value  is  1920000  KB.

Encryption Algorithm

From the list, select the algorithm to negotiate the security association (SA):

3DES.  Triple  DES.  This  is  the  default  algorithm.

None.  No  encryption  algorithm.

DES.  Data  Encryption  Standard  (DES).

AES-128.  Advanced  Encryption  Standard  (AES)  with  a  128-bit  key  size.

AES-192.  AES  with  a  192-bit  key  size.

AES-256.  AES  with  a  256-bit  key  size.
