扩展访问控制列表配置命令

配置TCP/UDP协议的扩展访问列表：
rule {normal|special}{permit|deny}{tcp|udp}source {|any}destination |any}
[operate]

配置ICMP协议的扩展访问列表：
rule {normal|special}{permit|deny}icmp source {|any]destination {|any]
[icmp-code] [logging]

less-than portnumber 小于
not-equal portnumber 不等
range portnumber1 portnumber2 区间
