Parameter

Description

No Parameters

Shows the applicable built-in usage.

-a <IPv4 Address>[/<Subnet Prefix>]

Adds the specified IPv4 address to the Accelerated SYN Defender whitelist.

  • <IPv4 Address> - Can be an IPv4 address of a network or a host.
  • <Subnet Prefix> - Must specify the length of the subnet mask in the format /<bits>.

    Optional for a host IPv4 address.

    Mandatory for a network IPv4 address.

    Range - from /1 to /32.

    Important - If you do not specify the subnet prefix explicitly, this command uses the subnet prefix /32.

Examples:

  • For a host:

    192.168.20.30

    192.168.20.30/32

  • For a network:

    192.168.20.0/24

-a <IPv6 Address>[/<Subnet Prefix>]

Adds the specified IPv6 address to the Accelerated SYN Defender whitelist.

  • <IPv6 Address> - Can be an IPv6 address of a network or a host.
  • <Subnet Prefix> - Must specify the length of the subnet mask in the format /<bits>.

    Optional for a host IPv6 address.

    Mandatory for a network IPv6 address.

    Range - from /1 to /128.

    Important - If you do not specify the subnet prefix explicitly, this command uses the subnet prefix /128.

Examples:

  • For a host:

    2001:0db8:85a3:0000:0000:8a2e:0370:7334

    2001:0db8:85a3:0000:0000:8a2e:0370:7334/128

  • For a network:

    2001:cdba:9abc:5678::/64

-d <IPv4 Address>[/<Subnet Prefix>]

Removes the specified IPv4 address from the Accelerated SYN Defender whitelist.

  • <IPv4 Address> - Can be an IPv4 address of a network or a host.
  • <Subnet Prefix> - Optional. Must specify the length of the subnet mask in the format /<bits>.

    Optional for a host IPv4 address.

    Mandatory for a network IPv4 address.

    Range - from /1 to /32.

    Important - If you do not specify the subnet prefix explicitly, this command uses the subnet prefix /32.

-d <IPv6 Address>[/<Subnet Prefix>]

Removes the specified IPv6 address from the Accelerated SYN Defender whitelist.

  • <IPv6 Address> - Can be an IPv6 address of a network or a host.
  • <Subnet Prefix> - Optional. Must specify the length of the subnet mask in the format /<bits>.

    Optional for a host IPv6 address.

    Mandatory for a network IPv6 address.

    Range - from /1 to /128.

    Important - If you do not specify the subnet prefix explicitly, this command uses the subnet prefix /128.

-F

Removes (flushes) all entries from the Accelerated SYN Defender whitelist.

-l /<Path>/<Name of File>

Loads the Accelerated SYN Defender whitelist entries from the specified plain-text file.

Note - To replace the current whitelist with the contents of a new file, use both the -F and -l parameters on the same command line.

Important:

  • You must manually create and configure this file with the touch or vi command.
  • You must assign at least the read permission to this file with the chmod +x command.
  • Each entry in this file must be on a separate line.
  • Each entry in this file must be in this format:

    <IPv4 Address>[/<Subnet Prefix>]

  • SecureXL ignores empty lines and lines that start with the # character in this file.

-L

Loads the Accelerated SYN Defender whitelist entries from the plain-text file with a predefined name:

$FWDIR/conf/synatk-whitelist-v4.conf

Security Gateway automatically runs these commands {fwaccel | fwaccel6} synatk whitelist -L during each boot.

Note - To replace the current whitelist with the contents of a new file, use both the -F and -L parameters on the same command line.

Important:

  • This file does not exist by default.
  • You must manually create and configure this file with the touch or vi command.
  • You must assign at least the read permission to this file with the chmod +x command..
  • Each entry in this file must be on a separate line.
  • Each entry in this file must be in this format:

    <IPv4 Address>[/<Subnet Prefix>]

  • SecureXL ignores empty lines and lines that start with the # character in this file.

-s

Shows the current Accelerated SYN Defender whitelist entries.

Example

[Expert@MyGW:0]# fwaccel synatk whitelist -a 192.168.20.0/24

[Expert@MyGW:0]# fwaccel synatk whitelist -s

192.168.20.0/24

[Expert@MyGW:0]# fwaccel synatk whitelist -d 192.168.20.0/24

[Expert@MyGW:0]#

[Expert@MyGW:0]# fwaccel synatk whitelist -a 192.168.40.55

[Expert@MyGW:0]# fwaccel synatk whitelist -s

192.168.40.55/32

[Expert@MyGW:0]# fwaccel synatk whitelist -d 192.168.40.55
