specified source port.
The field allows you to enter the following options:
– You specify a port with a single numerical value, e.g.
21
.
– You specify multiple individual ports with numerical values
separated by commas, e.g.
21,80,110
.
– You specify a port range with numerical values connected by
dashes, e.g.
2000-3000
.
– You can also combine ports and port ranges, e.g.
21,2000-
3000,65535
.
The field allows you to specify up to 15 numerical values. If you
enter
