You have the following options for allowing access:
● Allow globally
Here, you use simple, predefined firewall rules. The enabled services are valid for all
nodes on the relevant interfaces. Full access is allowed for the specified direction.
– vlan1: Allows access from the internal network to the device
– ppp0 / usb0: Allows access from the external network to the device
The firewall rule for the opposite direction is permitted by stateful packet inspection.
● Allow certain services
Here, you define firewall rules that allow individual services for a single node or all
services for the node for access to the station or network.
In this example, configure the firewall rule that only allows the device with IP address
192.168.100.20 access to the device. The service HTTP (TCP port 80) is required for
access.
