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.
