Note: Some applications, such as FTP , TFTP , PPTP , and H 323,
require the support of special specific Application Level Gateway
(
ALG ) modules in order to work inside the local network. Data
packets associated with these applications contain information that
allows them to be routed correctly. An
ALG is needed to handle
these packets and ensure that they reach their intended destina-
tions. The Router is equipped with a robust list of
ALG modules in
order to enable maximum functionality in the local network. The
ALG is automatically assigned based on the destination port.
How many computers can use a service or play a game simultaneously? Well, the
answer may be a bit confusing. All the computers on the network can behave as
clients and use a specific service simultaneously. Being a client means the com-
puter within the network initiates the connection; for example, a computer on the
network can open an
FTP connection with an FTP server on the Internet. But only
one computer on the network can operate as a server and respond to requests from
computers on the Internet (outside the local network).
