Allowed Applications
Enable those applications you wish to give access to the
Internet while the Port Filtering feature is enabled. All other
applications will be blocked.
These allowed application rules are used to open single or
multiple ports on your HotSpot when it senses data sent to
the Internet via these applications.
Select All Applications: selects all applications listed below to
be allowed to pass through and access the Internet.
The following is a list of the allowed applications:
• DNS (Domain Name Server): is a technology used for
managing the names of Web sites and other Internet domains.
DNS technology allows you to type names into your Web
browser like samsung.com and have your computer
automatically find that IP address on the Internet.
Note: DNS (Domain Name Server) should always be enabled
when using Port Filtering. Without DNS, it is not possible
to convert a Domain name (for example, www.msn.com)
to an IP address. DNS is used by E-mail, FTP, and many
other protocols as well as by Web browsers.
• HTTP (Hypertext Transfer Protocol): is the data transfer protocol
used on the Web.
• HTTPS (Hypertext Transfer Protocol over TLS/SSL): is a secured
data transfer protocol (using TCP). This transfers hypertext
requests between both servers and your browser.
• FTP (File Transfer Protocol): is a network protocol used to copy
files from one location on the Web to another.
• E-mail(POP3): also known as Post Office Protocol, is a
standard protocol used by local e-mail applications/clients to
retrieve email from a remote server.
• E-mail (IMAP): also known as Internet Message Access
Protocol, is used for retrieving remote email messages.
• VPN (Virtual Private Network): is a private network that is
extended externally and allows you to securely communicate
over a public network.
• Telnet: is a network protocol that is used to log onto another
computer on the same local network.
• RTP (Realtime Transport Protocol): is an Internet protocol used
for transferring both audio and video data.
