Enable PreDefined Service
The following screen will appear if you click the
enable
button after selecting a service from the
Service Name
drop-down menu of the
Port Forwarding
screen (
Security > Services > Port Forwarding > Enable PreDefined
Service
). This screen allows you to add predefined and custom-defined applications to your
Port Forwarding
Service Name
drop-down menu. You can enable the selected service as a host service or a dynamic service. If you
change the settings in this screen, click
apply
and then
OK
. If you click
back
or
Cancel
, the screen will return to its
previous settings.
For host services, all the rules of the selected service are applicable only for the selected host connected to the
modem. Dynamic service will enable all the rules in the service as dynamic rules; that is, rules are applicable for all
devices connected to the modem. Traffic from the outside network coming to the modem needs to be directed to a
particular host connected to the modem; therefore, any service that contains a rule for inbound traffic (such as
having direction as “in”) cannot be enabled as a dynamic service. A predefined service can be enabled in any
direction with the proper mode selected (host service or dynamic service). Dynamic application is not applicable for
services having direction as “Inbound Only” or “Both.”
