source_host_address
The IP address of the source host to filter against expressed in IPv4 dotted-decimal notation.
dest_host_address
The IP address of the destination host to filter against expressed in IPv4 dotted-decimal notation.
dest_address
The IP address(es) to which the packet is to be sent.
This option is used to filter all packets to a specific IP address or a group of IP addresses.
When specifying a group of addresses, the initial address is configured using this parameter. The range can
then be configured using the
This option is used to filter all packets to a specific IP address or a group of IP addresses.
When specifying a group of addresses, the initial address is configured using this parameter. The range can
then be configured using the
dest_wildcard
parameter.
dest_wildcard
This option is used in conjunction with the
dest_address
option to specify a group of addresses for which
packets are to be filtered.
The mask must be entered as a complement:
The mask must be entered as a complement:
Zero-bits in this parameter mean that the corresponding bits configured for the
dest_address
parameter must be identical.
One-bits in this parameter mean that the corresponding bits configured for the
dest_address
parameter must be ignored.
Important:
The mask must contain a contiguous set of one-bits from the least significant bit (LSB). Therefore,
allowed masks are 0, 1, 3, 7, 15, 31, 63, 127, and 255. For example, acceptable wildcards are 0.0.0.3, 0.0.0.255, and
0.0.15.255. A wildcard of 0.0.7.15 is not acceptable since the one-bits are not contiguous.
0.0.15.255. A wildcard of 0.0.7.15 is not acceptable since the one-bits are not contiguous.
fragment
Indicates packet redirection is to be applied to IP packet fragments only.
Usage
Block IP packets when the source and destination are of interest.
Important:
The maximum number of rules that can be configured per ACL varies depending on how the ACL is
to be used. For more information, refer to the Engineering Rules appendix in the System Administration Guide.
Important:
Also note that “redirect” rule definitions are ignored for ACLs applied to specific subscribers or all
subscribers facilitated by a specific context.
Example
The following command defines a rule definition that redirects packets to the charging service named
chgsvc1
, and downlink IP packets coming from the host with the IP address
198.162.100.25
, and
fragmented packets for any destination are matched:
redirect css service chgsvc1 downlink ip host 198.162.100.25 any fragment
The following sets the insertion point before the rule definition above:
