220 AT-WR4500 Series - IEEE 802.11abgh Outdoor Wireless Routers
RouterOS v3 Configuration and User Guide
every - match every every+1th packet. For example, if every=1 then the rule matches every 2nd
packet
counter - specifies which counter to use. A counter increments each time the rule containing nth match
matches
packet - match on the given packet number. The value by obvious reasons must be between 0 and
every. If this option is used for a given counter, then there must be at least every+1 rules with this
option, covering all values between 0 and every inclusively.
out-bridge-port (name) - actual interface the packet is leaving the router through (if bridged, this
property matches the actual bridge port, while out-interface - the bridge itself)
out-interface (name) - interface the packet is leaving the router through (if the interface is bridged, then
the packet will appear to leave through the bridge interface itself)
packet-mark (text) - matches packets marked via mangle facility with particular packet mark
packet-size (integer: 0..65535-integer: 0..65535{0,1}) - matches packet of the specified size or size range
in bytes
min - specifies lower boundary of the size range or a standalone value
max - specifies upper boundary of the size range
port (port{0-16}) - matches if any (source or destination) port matches the specified list of ports or port
ranges (note that the protocol must still be selected, just like for the regular src-port and dst-port
matchers)
protocol (ddp | egp | encap | ggp | gre | hmp | icmp | idrp-cmtp | igmp | ipencap | ipip | ipsec-ah | ipsec-
esp | iso-tp4 | ospf | pup | rdp | rspf | st | tcp | udp | vmtp | xns-idp | xtp | integer) - matches particular IP
protocol specified by protocol name or number. You should specify this setting if you want to specify
ports
psd (integer,time,integer,integer) - attempts to detect TCP and UDP scans. It is advised to assign lower
weight to ports with high numbers to reduce the frequency of false positives, such as from passive mode
FTP transfers
WeightThreshold - total weight of the latest TCP/UDP packets with different destination ports coming
from the same host to be treated as port scan sequence
DelayThreshold - delay for the packets with different destination ports coming from the same host to
be treated as possible port scan subsequence
LowPortWeight - weight of the packets with privileged (<=1024) destination port
HighPortWeight - weight of the packet with non-priviliged destination port
random (integer) - match packets randomly with given propability
routing-mark (name) - matches packets marked by mangle facility with particular routing mark
same-not-by-dst (yes | no) - specifies whether to account or not to account for destination IP address
when selecting a new source IP address for packets matched by rules with action=same
src-address (IP address/netmask | IP address-IP address) - specifies the address range an IP packet is
originated from. Note that console converts entered address/netmask value to a valid network
address, i.e.:1.1.1.1/24 is converted to 1.1.1.0/24
src-address-list (name) - matches source address of a packet against user-defined address list
src-address-type (unicast | local | broadcast | multicast) - matches source address type of the IP packet,
one of the:
unicast - IP addresses used for one point to another point transmission. There is only one sender and
one receiver in this case
local - matches addresses assigned to router's interfaces
broadcast - the IP packet is sent from one point to all other points in the IP subnetwork
multicast - this type of IP addressing is responsible for transmission from one or more points to a set of
other points
src-mac-address (MAC address) - source MAC address
src-port (integer: 0..65535-integer: 0..65535{*}) - source port number or range
tcp-mss (integer: 0..65535) - matches TCP MSS value of an IP packet
time (time-time,sat | fri | thu | wed | tue | mon | sun{+}) - allows to create filter based on the packets'
arrival time and date or, for locally generated packets, departure time and date
to-addresses (IP address-IP address{0,1}; default: 0.0.0.0) - address or address range to replace original
address of an IP packet with
to-ports (integer: 0..65535-integer: 0..65535{0,1}) - port or port range to replace original port of an IP
packet with
