Enter the keyword deny to configure a filter to drop packets meeting this condition. Enter the keyword permit to configure a filter to forward packets meeting this criteria. Enter a number from 0 to 255 to filter based on the protocol identified in the IP protocol header. Enter the keyword icmp to configure an ICMP access list filter. Enter the keyword ip to configure a generic IP access list. The keyword ip specifies that the access list will permit all IP protocols. Enter the keyword tcp to configure a TCP access list filter. Enter the keyword udp to configure a UDP access list filter. Enter the IP address of the network or host from which the packets were sent. Enter a network mask in /prefix format (/x) or A.B.C.D. The mask, when specified in A.B.C.D format, may be either contiguous or non-contiguous. Enter the keyword any to specify that all routes are subject to the filter. Enter the keyword host followed by the IP address to specify a host IP address. (OPTIONAL) Enter one of the following logical operands: • eq = equal to • neq = not equal to • gt = greater than • lt = less than • range = inclusive range of ports (you must specify two ports for the port parameter.) (OPTIONAL) Enter the application layer port number. Enter two port numbers if using the range logical operand. Range: 0 to 65535 The following list includes some common TCP port numbers: • 23 = Telnet • 20 and 21 = FTP • 25 = SMTP • 169 = SNMP Enter the IP address of the network or host to which the packets are sent. (OPTIONAL) Enter an ICMP message type, either with the type (and code, if necessary) numbers or with the name of the message type (ICMP message types are listed in Table 9-2). Range: 0 to 255 for ICMP type; 0 to 255 for ICMP code (OPTIONAL) Enter the keyword count to count packets processed by the filter. (OPTIONAL) Enter the keyword byte to count bytes processed by the filter. 248 | Access Control Lists (ACL)
