INTRODUCTION

Dualog Endpoint protects all devices against traffic from unknown devices. Sometimes this causes network services to fail - e.g. if you try to connect to a computer using Remote Desktop or Windows File Sharing.

To allow communication between devices - for instance in the business network on a ship - the network must be marked as “trusted”. When a network is marked as trusted, Dualog Endpoint allows all traffic that would otherwise be allowed in the Windows Firewall to be allowed.

CONFIGURE TRUSTED NETWORKS

There are two ways of configuring networks as trusted in Dualog Endpoint:

1. Manually configuring one network as trusted
2. Automatically configuring all networks according to a network mask

MANUALLY CONFIGURING NETWORK AS TRUSTED

If you manually want to configure a network as trusted in Dualog Endpoint, you can do so using the “Network” tab on the Dualog Portal. Select the ship you want to configure.

Finally, to configure the network as trusted, click the three-dot menu to the right of the network you want to configure and slide the “Trusted network” slider.

AUTOMATICALLY CONFIGURE TRUSTED NETWORKS

If the fleet has a standardised network configuration, you can configure a default trusted network that will automatically be applied to new ships that are installed. 

1. To configure a new trusted network, go to the Configurations tab in the Dualog Portal.
2. Scroll down to the “Trusted Networks” area and click “Add network”.
3. Specify a network mask and click “Save”.
4. See “Network Specification” below for details on the network mask:

When you have created the trusted network zone, all new networks that match the network mask specified will automatically be trusted. Existing networks are not modified - but you may run a manual sync by clicking the “Sync”-button.

To see what networks are covered by the network mask, you can click the “List”-button.

Note: If you specify the network mask 0.0.0.0 / 0, all networks will be marked as trusted.

(OPTIONAL) VALIDATE CONFIGURATION ON A CLIENT

After the network is configured as trusted in the portal, the service starts updating all the installations in that network. Note that this could take up to 10-15 minutes.

1. To validate that trusted network settings are applied, you can inspect the settings of one of the clients in the network.
2. In the client’s ESET Endpoint software, go to “Setup” → “Advanced Setup” → “Network Protection” → “Zones” and click “View”.
3. You should see the trusted network listed in the top setting if everything is OK.
