Forwarding specific inbound-connections to the SMO (asg_excp_conf)

You can configure the Security GroupClosed A logical group of Security Gateway Modules that provides Active/Active cluster functionality. A Security Group can contain one or more Security Gateway Modules. Security Groups work separately and independently from each other. To the production networks, a Security Group appears a single Security Gateway. to forward specific inbound connections to the SMOClosed See "SMO". Security Group Member.

Important:

  • This command supports only IPv4 connections.

  • This command does not support local outgoing connections that the Security Group initiates.

  • In VSX mode, you must run this command in the context of the applicable Virtual System.

  • This command supports a maximum of 15 exceptions

    (in VSX mode, this limit is global for all Virtual Systems).

  • These exceptions are saved in the $FWDIR/tmp/tmp_exception_entries.txt file (IPv4 addresses are converted to a special format).

Syntax

asg_excp_conf

      clear

      del <ID>

      get

      set <type> <src_ip> <sport> <dst_ip> <dport>

Parameters

Parameter

Description

clear

Clears the table with all exception entries.

del <ID>

Deletes a specific exception entry by its ID.

Use the "get" parameter to see the IDs.

ID numbers start from 0 (zero).

get

Shows the table with all exception entries.

set <type> <src_ip> <sport> <dst_ip> <dport>

Configures a new exception entry.

Notes:

  • This command does not support wildcard characters (* or ?) or the word "any".

    You must always configure the exact values of the connection 4-tuple.

  • The order of these arguments is predefined (for example, "<src_ip>" is always the second argument).

Arguments:

  • <type>

    Configures the match condition - which connection parameters the Security Group must consider.

    Although you configure all connection parameters, the Security Group uses only specific parameters determined by the <type> value.
