The tcpall state engine is used for TCP service definitions that specify a large range of ports such as the predefined service tcp all. because it has a lower precedence than tcp, ftp, rsh, or realaudio, it does not override any of those services. Normally, this state engine is only used for the predefined service tcp all.
The discriminator for the tcpall state engine is the port number of the TCP service.
The tcpall state engine has the following parameter:
Lifetime of idle connection in seconds - Specifies the lifetime of an idle connection (default = 86400 seconds or 24 hours)
