ProSAFE 8-Port or 16-Port Gigabit Smart Managed Switch Model GS418TPP, GS510TLP, and GS510TPP - If you select the Range radio button, the IP ACL rule matches only if the Layer 4 destination port number is within the specified port range. The starting port, ending port, and all ports in between are a part of the Layer 4 port range. The Start Port and End Port fields identify the first and last ports that are part of the port range. They values can range from 0 to 65535. You can either select the enter the port range yourself or select one of the following protocols from the menu: • The destination IP TCP port range names are domain, echo, ftp, ftpdata, www-http, smtp, telnet, pop2, pop3, and bgp. • The destination IP UDP port range names are domain, echo, snmp, ntp, rip, time, who, and tftp. Each of these values translates into its equivalent port number, which is used as both the start and end of the port range. Select Other from the menu to enter a port number. If you select Other from the menu but leave the field blank, it means any. The wildcard mask determines which bits are used and which bits are ignored. A wildcard mask of 0.0.0.0 indicates that none of the bits are important. A wildcard of 255.255.255.255 indicates that all of the bits are important. • IGMP Type. If you specify the IGMP type, the IP ACL rule matches the specified IGMP message type. Possible values are in the range 0 to 255. If this field is left empty, it means any. • ICMP. Select either the Type or Message radio button: - If you select the Type radio button, note the following: • The Type and Code fields are enabled only if the protocol is ICMP. Use these fields to specify a match condition for ICMP packets: • The IP ACL rule matches the specified ICMP message type. Possible type numbers are in the range from 0 to 255. • If you specify information in the Message field, the IP ACL rule matches the specified ICMP message code. Possible values for the code can be in the range from 0 to 255. • If these fields are left empty, it means any. - If you select the Message radio button, select the type of the ICMP message to match with the selected IP ACL rule. Specifying a type of message implies that both the ICMP type and ICMP code are specified. The ICMP message is decoded into the corresponding ICMP type and ICMP code within the ICMP type. The IPv4 ICMP message types are echo, echo-reply, host-redirect, mobile-redirect, net-redirect, net-unreachable, redirect, packet-too-big, port-unreachable, source-quench, router-solicitation, router-advertisement, ttl-exceeded, time-exceeded, and unreachable.
