Then, add a schedule rule (for more details about schedule rules, see the “Advanced Settings” chapter of this manual).

☞Note: Some applications, such as FTP, TFTP, PPTP, and H323, 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).
