DESCRIPTION
You can use the management-ip-rules component to configure network firewall rules that are applied to all
management interface traffic. The network software compares IP packets to the criteria specified in these
rules. If a packet matches the criteria then the system takes the action specified by the rule. If a packet
does not match a rule then the software compares the packet against the next rule. If a packet does not match
any rule the packet is accepted.
For configuration sync management-ip-rules are synced to the devicegroup that has a type field of sync-
failover. See "cm config-sync".
MATCHING AN IP PACKET
You can use this TMSH component to match against any or all of the following properties of an IP packet:
source address
source port
the packet's source VLAN
destination address
destination port
the higher-level protocol in the packet's payload
If you match against more than one of these items, a packet must pass all of your tests to successfully match.
For example, if you match against a source subnet and several destination ports, a packet must originate from
the given subnet and must also have one of the specified destination ports.
RULE ORDER
Rules are evaluated in the order that you specify. You can use the list management-ip-rules command to see the
current rule order. As you add or modify rules in this component, you can use the place-before rule-name or
place-after rule-name option to choose the rule's place in the sequence.
Rule order can determine whether or not a packet is dropped. Consider the following rules:
rule_a, matches source addresses against 172.16.0.0 and ACCEPTS all packets that match.
rule_d, matches source addresses against 172.16.39.0 and DROPS all packets that match.
Also consider a packet from a host at 172.16.39.55. If rule_a appears before rule_d in the rule list, the
packet's source address matches rule_a first and the software accepts it. The software never reaches rule_d
for comparison. If rule_d appears first instead, the packet's source address now matches rule_d; in this case,
the software drops the packet.
EXAMPLES
modify management-ip-rules rules add { reject-internal-net { source { addresses replace-all-with {
172.27.0.0/16 } } action reject place-before first } }
Creates a rule entry at the beginning of the list that rejects traffic from the 172.27.0.0 network.
modify management-ip-rules rules add { reject-insecure-ports { rule-list block_bad_mgmt place-before first } }
Adds a sub rule list to the management-IP firewall. Use the "security firewall rule-list" component to create
a custom rule list.
list management-ip-rules
security firewall management-ip-rules {
rules {
reject-insecure-ports {
rule-list block_bad_mgmt
}
reject-internal-net {
action reject
source {
addresses {
172.27.0.0/16 { }
}
}
}
}
}
Displays the current list of management-firewall rules.
modify management-ip-rules rules delete { reject-internal-net }
Removes the reject-internal-net rule from the management-IP firewall.
OPTIONS
description
Your description for the management-firewall rules.
rules
Adds, deletes, or replaces a firewall rule.
add Creates a new rule, which you specify next with a unique string in curly braces ({}). Use the place-
before or place-after option inside the curly braces to determine the order of the rule. If this is
the first rule, use the replace-all-with option instead of add.
delete
Deletes the rule that you specify next, in curly braces ({}).
modify
Modifies the existing rule that you specify next, in curly braces ({}). After the rule name, enter
the new configuration settings for the rule inside a nested set of curly braces.
replace-all-with
Replaces the current set of global rules with the rule(s) that you specify next, in curly braces
({}). Use this option for the first management rule.
none Empties the list of management-firewall rules. This implicitly accepts all packets on the management
interface.
Enter the name of a rule to be added or modified, then enter an open curly brace ({), one or more of the
following options, and a closed curly brace (}).
action
Specifies the action that the system takes when a packet matches the rule.
accept
Specifies that a matching packet should be accepted. The security software stops comparing a
matching packet to any other management-firewall rules.
accept-decisively
This option is functionally the same as accept.
drop Specifies that a matching packet should be silently dropped. The security software sends
nothing back to the packet source, and it does not compare the packet to any other management-
firewall rules.
reject
Specifies that a matching packet should be dropped. For TCP-based protocols, the security
software sends a TCP reset (with the RST flag raised) back to the source. For other protocols,
reject is equivalent to drop.
app-service
Associates the management-rule list with a particular Application Service. An Application Service is
a major component of an iApp, an advanced configuration tool for creating and maintaining similar
applications on multiple servers. The asm module has components for working with iApps.
description
Your description for the current rule.
destination
Matches against each packet's destination IP and/or destination port. The next options choose the
matching criteria.
address-lists
Specifies a list of IP-address lists (see "security firewall address-list") to compare against
the packet's destination address.
This list uses the same add, delete, none, and replace-all-with options described above for
rules, as well as a default option.
addresses
Specifies a list of IP addresses and/or subnets to compare against the packet's destination
address.
The format for an IPv4 address is a.b.c.d[/prefix]. The general format for an IPv6 address is
a:b:c:d:e:f:g:h[/prefix]; you can shorten this by eliminating leading zeros from each field
(for example, you can shorten "2001:0db7:3f4a:09dd:ca90:ff00:0042:8329" to
"2001:db7:3f4a:9dd:ca90:ff00:42:8329"), and/or by removing the longest contiguous field of
zeros (for example, you can shorten "2001:0:0:0:c34a:0:23ff:678" to "2001::c34a:0:23ff:678").
TMSH accepts any valid text representation of IPv6 addresses, as defined in RFC 2373 (see
).
To edit this list, use the same add, delete, modify, none, and replace-all-with options
described above for rules.
port-lists
Specifies a collection of port lists (see "security firewall port-list") to compare against the
packet's destination port. If you use this option to specify a port list, a packet only matches
if it's destination port matches a port on these lists.
This list uses the same add, delete, none, and replace-all-with options described above for
rules, as well as a default option.
ports
Specifies a list of ports and port ranges to compare against the packet's destination port.
To edit this list, use the same add, delete, modify, none, and replace-all-with options
described above for rules.
icmp Specifies a list of ICMP types and codes to compare against the packet. You must set the ip-protocol
option to "icmp" for this option to function. If you use this option, the current rule only matches
ICMP packets that have the ICMP properties you specify here. You can add, delete, or modify (that
is, change the description of) any entry in the list, or replace-all-with a new set of entries that
you specify between curly braces ({}).
Use the standard integer identifiers to specify an ICMP type. For example: 3 is destination
unreachable and 3:1 is destination unreachable with a code of host unreachable. The official list of
ICMP types and codes is here: .
ip-protocol
Specifies the IP protocol to compare against the packet. This could be a layer-3 protocol (such as
ipv4 or ipv6), or a higher-level protocol like ospf, rdp, or icmp. If you specify this option, a
packet only matches if it uses the chosen protocol. Press the key for a full list of valid
protocols.
log Specifies whether the security software should write a log entry for all packets that match this
rule. You must also enable network filter logging in the "security log profile" component for this
option to have any effect. Note that the security software always increments the statistics counter
when a packet matches a rule, no matter how you set this option.
place-after [first | last | rule-name]
Specifies that a new rule should be placed after the first rule, the last rule, or the rule-name you
specify. If you are adding individual rules (as opposed to specifying replace-all-with), then you
must use place-before or place-after to specify the rule's position in the list.
place-before [first | last | rule-name]
Specifies that a new rule should be placed before the first rule, the last rule, or the rule-name
you specify. If you are adding individual rules (as opposed to specifying replace-all-with), then
you must use place-before or place-after to specify the rule's position in the list.
rule-list
Specifies a full rule list instead of a customized rule that you might define with the other
options. See "security firewall rule-list". If you use this option, then only the schedule and
status options are valid; the tmsh software rejects any other options that you attempt to use with
rule-list.
schedule
Specifies a schedule for the rule. See "security firewall schedule". If you omit this option, the
rule or rule list is enabled all the time.
If the rule refers to a rule-list, the rule-list is enabled according to the schedule. When the rule
list is enabled, the security software then honors the schedules defined within the rule-list.
source
Matches against each packet's source IP, source port, and/or source VLAN. The next options choose
the matching criteria.
address-lists
Specifies a list of address lists (see "security firewall address-list") to compare against the
packet's source address.
This list uses the same add, delete, none, and replace-all-with options described above for
rules, as well as a default option.
addresses
Specifies a list of IP addresses and networks to compare against the packet's source address.
The format for an IPv4 address is a.b.c.d. The general format for an IPv6 address is
a:b:c:d:e:f:g:h.
To edit this list, use the same add, delete, modify, none, and replace-all-with options
described above for rules.
port-lists
Specifies a collection of port lists (see "security firewall port-list") to compare against the
packet's source port. If you use this option to specify a port list, a packet only matches if
its source port matches a port on these lists.
This list uses the same add, delete, none, and replace-all-with options described above for
rules, as well as a default option.
ports
Specifies a list of ports and port ranges to compare against the packet's source port.
To edit this list, use the same add, delete, modify, none, and replace-all-with options
described above for rules.
vlans
Specifies a list of VLANs, VLAN groups, and tunnels to compare against the packet.
This list uses the same add, delete, none, and replace-all-with options described above for
rules, as well as a default option.
status
Specifies whether the rule is enabled, disabled or scheduled. A rule that is enabled is always
checked. A rule that is disabled is never checked. A rule that is scheduled is checked according to
the corresponding schedule configuration. A rule that is scheduled must have an associated schedule
configuration.
uuid Specifies how this rule UUID is assigned: assign a explict uuid based on RFC-4122, empty UUID (none
value), or an auto-generated uuid by system (auto-generated value) based on system wide
mode:[uuid-default-autogenerate mode] when creating a rule.
