Services
Click Access on the left side of the browser window, and then click the Services tab.
Note: The LAN In column is not displayed if NAT is enabled.
The Services window allows you to customize Network Access Rules by service. Services displayed
in the Services window relate to the rules in the Rules window, so any changes on the Services
window appear in the Rules window. The Default rule, at the bottom of the table, encompasses all
Services.
LAN Out
If the LAN Out check box is selected, you can access that service from your LAN on the Internet.
Otherwise, you are blocked from accessing that service. By default, the LAN Out check boxes are
selected.
DMZ In (Optional)
If the DMZ In is selected, users on the Internet can access the service on the DMZ. Otherwise, they
are blocked from accessing the service on the DMZ. By default, DMZ In is selected. The DMZ In
column does not appear in the Web Management Interface for the SonicWALL SOHO3 and TELE3
which do not have a separate DMZ port.
LAN In
If a LAN In checkbox is enabled, users on the Internet can access all computers on your network for
that service. By default, LAN In checkboxes are not enabled. Use caution when enabling a LAN In
service.
Alert If an Alert Icon appears next to a LAN Out, LAN In, or DMZ In check box, a rule in the Rules
window modifies that service.
