Network Connection Inactivity Timeout
If a connection to a remote server remains idle for more than five minutes, the SonicWALL
closes the connection. Without this timeout, Internet connections could stay open
indefinitely, creating potential security holes. You can increase the Inactivity Timeout if
applications, such as Telnet and FTP, are frequently disconnected.
Add Service
To add a service not listed in the Services window, click Access on the left side of the
browser window, and then click the Add Service tab.
The list on the right side of the window displays the services that are currently defined.
These services also appear in the Services window.
Two numbers appear in brackets next to each service. The first number indicates the
service's IP port number. The second number indicates the IP protocol type (6 for TCP, 17
for UDP, or 1 for ICMP).
Note: There can be multiple entries with the same name. For example, the default
configuration has two entries labeled “Name Service (DNS)”--for UDP port 53 and TCP port
53. Multiple entries with the same name are grouped together, and are treated as a single
service. Up to 128 entries are supported.
