Examples: Configure Applications

The following example shows an application protocol definition describing a special FTP application  running on port 78:

[edit applications]

application my-ftp-app {

    application-protocol ftp;

    protocol tcp;

    destination-port 78;

    timeout 100; # inactivity timeout for ftp service

}

The following example shows a special ICMP protocol (application-protocol icmp) of type 8 (ICMP echo):

[edit applications]

application icmp-app {

    application-protocol icmp;

    protocol icmp;

    icmp-type icmp-echo;

}

The following example shows a possible application set:

[edit applications]

application-set basic {

    http;

    ftp;

    telnet;

    nfs;

    icmp;

} 

The software includes a predefined set of well-known application protocols. The set includes applications for which the TCP and UDP destination ports are already recognized by stateless firewall filters.
