Related: The incoming packets are new, but associated with an already existing connection.
Established: The incoming packets are associated with an already existing connection.
New: The incoming packets are from a new connection.
In addition to a direction or network type, the firewall rules can also be matched to a state: Firewall rules configured under LAN Local will apply to traffic from the LAN (Corporate) network, destined for the UDM/USG itself.
Out: Applies to traffic that is exiting the interface (egress), destined for this network.įor example, firewall rules configured under LAN In will apply to traffic from the LAN (Corporate) network, destined for other networks.
In: Applies to traffic that is entering the interface (ingress), destined for other networks.
Local: Applies to traffic that is destined for the UDM/USG itself.
Guest v6: Contains IPv6 firewall rules that apply to the Guest network.īesides the network type, the firewall rules also apply to a direction.
LAN v6: Contains IPv6 firewall rules that apply to the LAN (Corporate) network.
Internet v6: Contains IPv6 firewall rules that apply to the Internet network.
Guest: Contains IPv4 firewall rules that apply to the Guest network.
LAN: Contains IPv4 firewall rules that apply to the LAN (Corporate) network.
Internet: Contains IPv4 firewall rules that apply to the Internet network.
The rules are grouped based on the type of network that they apply to. It is important to be aware of this index because incorrect placement may create the perception of a rule "not working". When creating a new rule, you can choose to apply it before or after the predefined rules. A lower number (top of the list) means that the rule is processed before the other rules. Additionally, UniFi will configure similar rules for each additional network you add.įirewall rules are executed in order of the Rule Index. UniFi pre-configures certain rules to optimize local network traffic, while preventing certain potentially dangerous internet traffic. They provide an incredibly intuitive interface that streamlines rule creation for common use-cases such as network isolation, parental controls, or even bandwidth limiting. We recommend most users configure the Firewall using Traffic Rules. UniFi Gateways include a powerful Firewall engine to provide maximum network security.
