Port Forwarding; Packet Filtering - Digi 6350-SR User Manual

Firewall settings

Port forwarding

Remote computers can access applications or services hosted on a local network with the Digi 6350-
SR/6355-SR by setting up port forwarding. It provides mapping instructions that direct incomming
traffic to the proper device on a LAN.
To configure port forwarding:
1. Under Firewall > Port Forwarding, click the Add button.
2. Select the relevant LAN Interface.
Note Select LAN unless custom interfaces were configured.
3. The IP version and Protocol can be left at their default values unless changes are required by
the request being serviced by this port-forwarding configuration.
4. Specify the public-facing Port for remote access.
5. In the To fields, specify the port and IP address associated with the intended destination
device.
6. If necessary, expand the Access Control List to create a white list that determines which
devices are authorized to leverage this particular forwarding route.
Note Both individual IP addresses and entire zones may be white listed.

Packet filtering

Enabled by default, packet filtering will monitor traffic going to and from the Digi 6350-SR/6355-SR.
The predefined settings are intended to block unauthorized inbound traffic while providing an
unrestricted flow of data from LAN to WAN.
