remove the rule from the screen 'Port Forwarding'. This can be useful when making
the service temporarily unavailable and when expecting to reinstate it in the future.
To temporarily disable a rule, clear the check box next to the service name.
To reinstate it at a later time, reselect the check box.
To remove a rule, click the action icon 'Remove' for the service; the service is
permanently removed.
How many computers can use a service or play a game simultaneously? All computers on
the network can use a specific service as clients simultaneously. Being a client means that
the computer within the network initiates the connection - for example, opens an FTP
connection with an FTP server on the Internet. But only one computer can serve as a
server, meaning responding to requests from computers on the Internet. Assigning a
specific computer as a server is done in the Port Forwarding section of Web-based
management.
