If Flag is checked the event is flagged for easier viewing in the event log. Block: Blocks the traffic which matched the rule.Īdditionally a session can be flagged.Pass: Allows the traffic which matched the rule to flow.It is up to you to decide to best fit for your network, whether you only want to block specific ports or you want to block everything and allow only a few services. Because of this, the Firewall does not block anything by default. In this scenario all inbound sessions are blocked by NAT except those explicitly allowed with port forwards.
Typically Untangle is installed as a NAT/gateway device, or behind another NAT/gateway device in bridge mode. Flagging a session marks it in the logs for reviewing in the event logs or reports, but has no direct effect on the network traffic. Firewall uses rules to determine to block/pass the specific session, and if the sessions is flagged. The Rules documentation describes how rules work and how they are configured. The Rules tab allows you to specify rules to Block, Pass or Flag traffic that crosses the Untangle. This displays the current status and some statistics. This section reviews the different settings and configuration options available for Firewall. The Firewall app provides the same functionality as the traditional "firewall" - the ability to use rules to control which computers and communicate on a network. The "Firewall" app itself is a traditional firewall used to block and/or flag TCP and UDP sessions passing through Untangle using rules. The "firewall" is often use interchangeably with "router" "gateway" and "UTM" or "Unified Threat Management"Įven the Untangle NGFW is a "next-gen" "firewall." There are also host-based "firewalls" that run on the local host computer. The term "Firewall" has grown to encompass many functionalities and has a wide array of meanings.
