New Custom Service
The following screen will appear if you click the
new custom service
button from the
Port Forwarding
screen
(
Security > Services > Port Forwarding > New Custom 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.
To create a service rule for outgoing traffic from the local network, select the desired protocol, and specify the port
range from which you want to allow traffic in medium firewall settings, direction as out, and port direction as “dst”
(if you want to check for destination port in outgoing traffic) or “src” (if you want to check for source port in
outgoing traffic).
If you want to allow incoming traffic from outside the network to the local network, create an “in” direction rule,
and select the port range on which you want to allow incoming traffic. Select LAN port on which this traffic needs
to be directed and the desired protocol.
These rules can be applied by enabling the service from the
Service Name
drop-down menu on the
Port
Forwarding
screen.
