Max. connections-- modifying the connections appropriately allows the router to open
more connections at the same time. But the max connections may be limited by the router
memory and too many connections will result in breakdown of the router due to insufficient
memory! Please modify this parameter carefully.
Timeout—modifying the connection timeout appropriately can reduce the connection
time of the occupied resources for better network performance. But the too long or too
short timeout may cause certain applications fail to work! Please modify such parameters
carefully.
Note:
A good understanding of network technology is required before modifying these network
connection parameters. Keep the default values if you are unsure of the roles of these
parameters!
