Action1 5 Documentation 5 Firewall Configuration

Firewall Configuration

Inbound and Outbound Connections Explained

The Action1 agent is designed to establish connections exclusively to the Action1 cloud servers – it’s always the agent that initiates contact, never the other way around. As a result, you only need to set up outbound firewall rules. Despite this one-way initiation, data transfer can and does occur in both directions: from the agent to the server and back again.

When a connection is established, the agent simply waits for instructions from the server. These directions might be to execute a policy or gather data for a report. The server sends these instructions either when prompted by the user via the Action1 Console or according to a preset schedule. Think of it like an orchestra: the conductor (the server) gives instructions, and the musicians (the agents) wait for and follow these instructions. The musicians are always attentive to the conductor’s directions, not the other way around.

There is one exception to the outbound-only rule: when Action1 agents on the same local network want to exchange software package parts via peer-to-peer (P2P) sharing. In these cases, the agents will accept inbound connections from their peers. Although it’s not mandatory, we recommend setting up inbound LAN-only firewall rules to facilitate this type of exchange.

(Recommended) Exchanging pieces of downloaded apps (P2P file sharing) that helps minimize the external bandwidth usage. The port should be open locally on managed endpoints to allow connections between agents in the local network. If the inbound communication between agents on the local network is not allowed, the agents will not be exchanging downloaded app pieces locally and always download in full from the cloud.
