DESCRIPTION
You can use the network-whitelist component to configure two types of
DoS network whitelists: 1) standard whitelist, up to eight entries; 2)
extended whitelist, up to the the number of entries specified by DB
variable dos.maxewlsize (range from 0 to 1024). Whitelists configured
this way can be applied to all traffic except those from the management
interface. Along with that you can use address-list to configure the
srcIP Global whitelist. To this address-list you need to attach the
address list objects. This address-list can be a nested list of fully
qualified address. Subnets and IP address ranges and geo-locations are
not allowed. The HSB hardware compares all incoming traffic to the
network-whitelist entries. If a match is found then it does not do DoS
vector checks for those packets. If a match is not found then DoS
vector checks are done on those packets. The network software does its
regular DoS vector checks on the incoming packets as usual. If a DoS
vector is hit then it compares that packet with the DoS network-
whitelist entries. If the packet matches an entry, then the system does
not increment the DoS vector that matched. If the packets does not
match a DoS network-whitelist entry then the matched DoS vector is
incremented and appropriate action is taken.
If an entry specifies more than one of the above items, a packet must
pass all of the items to successfully match. For example, if an entry
specifies a source subnet and a destination port, a packet must
originate from the given subnet and must also have the specified
destination port.
Either destination ip_address/prefixlen or source ip_address/prefixlen
can be specified in a network-whitelist entry. An ip_address/prefixlen
for both source and destination cannot be specified for an entry.
EXAMPLES
modify network-whitelist dos-network-whitelist description "bad
interfaces" entries add { re_telnet { ip-protocol tcp destination {
port telnet } } }
Creates a new entry called re_telnet. It matches any TCP packet whose
destination port is telnet.
modify network-whitelist dos-network-whitelist entries add { internal-
net { source { address 172.27.0.0/16 } } }
Creates an entry that matches traffic from the 172.27.0.0 network.
list network-whitelist

ip-protocol tcp
destination {
port telnet
}
}
internal-net {
source {
address 172.27.0.0/16
}
}
}
}
Displays the current list of DoS whitelist entries.
modify network-whitelist dos-network-whitelist entries delete {
internal-net }

OPTIONS
address-list
Specifies the object in security firewall address-list as the
srcIP Global whitelist.
description
Your description for the DoS network-whitelist entries.
entries
Adds, deletes, or replaces a standard network-whitelist entry, by
specifying an entry name. If an entry by the specified name does
not exist, it will be created.
add Creates a new entry, which you specify next with a unique
string in curly braces ({}).
delete
Deletes the entry that you specify next, in curly braces
({}). You can use delete {all} to empty the list of network-
whitelist entries, which has the same effect as using none
(see below).
modify
Modifies the existing entry that you specify next, in curly
braces ({}). After the entry name, enter the new
configuration settings for the entry inside a nested set of
curly braces.
replace-all-with
Replaces the current set of network-whitelist entries with
the entry(s) that you specify next, in curly braces ({}).
none Empties the list of network-whitelist entries.
Enter the name of a entry to be added or modified, then enter an
open curly brace ({), one or more of the following options, and a
closed curly brace (}).
description
Your description for the current entry.
destination
Matches against each packet's destination IP and/or
destination port.
address
Specifies an IP address and network 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 ).
port Specifies a port to compare against the packet's
destination port.
ip-protocol
Specifies the IP protocol to compare against the packet. This
could be any, icmp, igmp, tcp or udp. If you specify this
option, a packet only matches if it uses the chosen protocol.
match-ip-version
Specifies whether any/any6 in source/destination address is
to match 'any IPv4', 'any IPv6', or 'any IPv4 and any IPv6'
addresses. If match-ip-version is true, both source and
destination addresses must have the same IP address family.
If match-ip-version is false and both source and destination
addresses are any or any6, both addresses represent 'any IPv4
and IPv6 addresses'. If match-ip-version is false and only
one address is set to any or any6, the address is interpreted
based on the other IP address' family (IPv4 or IPv6). The
default is false.
source
Matches against each packet's source IP, and/or source VLANs.
address
Specifies an IP address and network 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.
vlans
Specifies either a vlan name or a range of vlanids to
compare against the packet. The range is specified as
vlanid/mask. For example if you specify "3200/8" then
the vlanid range will be 3200-3327.
extended-entries
Adds, deletes, or replaces an extended network-whitelist entry, by
specifying an entry name. If an entry by the specified name does
not exist, it will be created.
add Creates a new entry, which you specify next with a unique
string in curly braces ({}).
delete
Deletes the entry that you specify next, in curly braces
({}). You can use delete {all} to empty the list of network-
whitelist entries, which has the same effect as using none
(see below).
modify
Modifies the existing entry that you specify next, in curly
braces ({}). After the entry name, enter the new
configuration settings for the entry inside a nested set of
curly braces.
replace-all-with
Replaces the current set of network-whitelist entries with
the entry(s) that you specify next, in curly braces ({}).
none Empties the list of network-whitelist extended-entries.
Enter the name of a entry to be added or modified, then enter an
open curly brace ({), one or more of the following options, and a
closed curly brace (}).
description

destination port.
address
Specifies an IP address and network to compare against
the packet's destination address.

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

port Specifies a port to compare against the packet's
destination port.
ip-protocol
Specifies the IP protocol to compare against the packet. This
could be any, icmp, igmp, tcp or udp. If you specify this
option, a packet only matches if it uses the chosen protocol.
match-ip-version
Specifies whether any/any6 in source/destination address is
to match 'any IPv4', 'any IPv6', or 'any IPv4 and any IPv6'
addresses. If match-ip-version is true, both source and

Specifies an IP address and network 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.
vlans
Specifies either a vlan name or a range of vlanids to
compare against the packet. The range is specified as
vlanid/mask. For example if you specify "3200/8" then
the vlanid range will be 3200-3327.
EXAMPLES
modify security dos network-whitelist dos-network-whitelist address-
list [name]
It adds list1 objects to the global address-list. For configuring the
address list objects (list1) you can use the following examples:
create security firewall address-list list1 addresses [add |
delete] { 30.30.30.30 45:56:567:234:456::0 }
list security firewall address-list list1
security firewall address-list list1 {
addresses {
30.30.30.30 { }
45:56:567:234:456:: { }
} }
This is how you can list the address-list objects that you configured
for global whitelists list security dos network-whitelist address-list
security dos network-whitelist dos-network-whitelist {
address-list list1 }
