Adding Proxy Applications
The Proxy Applications configuration dialog box enables the ProxyServer systems administrator
to configure the set of applications available for proxying by the Firewall. This list includes many of
the most common port usages; however, not all port usages are included because increasing the
number of supported port usages may result in a possible decrease in performance speed and an
increased security risk.
Refer to RFC 1700 on the Internet which defines the Internet Protocol suite. RFC 1700 identifies the
parameters, such as Internet address, domain names, autonomous system numbers, protocol
numbers, port numbers, and many others. Once the necessary information has been determined,
you can add the application(s) to the supported list. Once it has this information, the Firewall will
route packets through to the Internet from the unknown software.
The option to add Proxy applications is important as new software programs are continually being
developed to perform useful tasks. For example, you may want to add new database managers,
spreadsheets, communications packages, graphics programs etc. -- anything that would make your
job easier.
Editing considerations might involve enabling/disabling protocols individually (both TCP and UDP are
enabled by default), changing the Port Name (i.e., Description) to something more easily identifiable,
or changing the range of port numbers to exclude/include other users. (Refer to the Firewall Helps
for details.)

Note: Adding applications may decrease performance speed and increase security risks; therefore,
you may want to delete unused or rarely used applications.
