IPSOURCE IPv4 specified source address and optional address mask via the MASK key-

word. Creates a IPv4 field mask entry if it doesn’t already exist and creates

a rule match entry.

SOURCEMASK works with the IPSOURCE match rule field to match on

any IPv4 packet with the specified IP source address. The value is specified

as a mask for the IPSOURCE field. For example, an IPSOURCE of

192.168.1.0 with a SOURCEMASK of 255.255.255.0 matches 192.168.1.0

to 192.168.1.255. If no mask is provided then 255.255.255.255 is assumed.

The SOURCEMASK must be a contiguous series of bits starting with the

MSB. For example, 255.255.240.00 would be valid, but 255.0.255.0 would

not.

IPDEST IPv4 specified destination address and optional address mask via the MASK

keyword. Creates a IPv4 field mask entry if it doesn’t already exist and cre-

ates a rule match entry.

DESTMASK works with the IPDEST match rule field to match on any IPv4

packet with the specified IP destination address. The value is specified as a

mask for the IPDEST field. For example, an IPDEST of 192.168.1.0 with a

DESTMASK of 255.255.255.0 matches 192.168.1.0 to 192.168.1.255. If no

mask is provided then 255.255.255.255 is assumed. The DESTMASK must

be a contiguous series of bits starting with the MSB. For example,

255.255.240.00 would be valid, but 255.0.255.0 would not.

IPPROTOCOL IP protocol field value to match. The command will accept:

TCP

UDP

ICMP

IGMP

a protocol number.

UDPPORTSRC The value of the UDP source port to match.

UDPPORTDEST The value of the UDP destination port to match.

TCPPORTSRC The value of the TCP source port to match.

TCPPORTDEST The value of the TCP destination port to match.
