For that reason, for these addresses, you`ll also not see any activity reported in the reports. The difference from Policy-based whitelisting is that these do not enter any packet processing and are directly forwarded at the interface level.

To get help about Exempted VLANs & Networks use full help toggle.Įxempted VLANs and Network addresses are bypassed from any Zenarmor processing. Zenarmor Users have to configure these interfaces according to their monitoring requirements On the Zenarmor configuration page, there are a number of interfaces available depending on the model of the Zenarmor installed device. A network interface is generally a network interface card (NIC), but does not have to have a physical form. Interface Selection Ī network interface is the point of interconnection between a computer and a private or public network. With Hardware Assistant Bypass adapters, your device can act like a simple cable when there's a software/hardware problem, when Zenarmor is shut down or even when the machine is powered off. Currently only Silicom Bypass Adapters are supported. This mode supports Hardware Assisted Bypass technologies.

In this mode, it's not possible to make use of other existing OPNsense functionality like firewalling, VPN and other plug-ins since Zenarmor will bypass the Operating System and your device will act as a transparent filtering appliance. This experimental deployment mode allows you to be able to deploy Zenarmor like an Inline Web Secure Gateway. Bridge Mode (L2 Bridge Mode, Reporting + Blocking) With Emulated Netmap Driver Īs discussed above, if you suspect your Ethernet driver does not play well with netmap, you can use this option to be able to continue using Zenarmor with all of the functionality.īe noted that the Emulated driver is not as performant as the Native Netmap driver. If you suspect that your ethernet driver does not play well with netmap, then your best bet is using 元 mode with the Emulated Netmap Driver. Netmap can be picky when it comes to driver compatibility. With Native Netmap Driver īeing the default deployment option, this option allows you to be able to make use of native netmap performance with regard to Ethernet drivers. This mode utilizes netmap(4), the underlying packet processing subsystem of the FreeBSD operating system. In this mode, you can both do reporting and enjoy all of the filtering functionalities of the software. Routed Mode is the option where you deploy Zenarmor on top of the firewall and you still make use of the firewall's other services like 元/L4 filtering, routing, VPN and other plug-ins that are available. Routed Mode (元 Mode, Reporting + Blocking) If you're having trouble with the netmap subsystem and still want to make use of Zenarmor's advanced reporting capabilities, this is the best option. In this mode, it's not possible to do blocking. Zenarmor grabs a copy of packets from the configured interfaces and provides you with a wealth of information through its reporting. Passive mode is like Suricata's IDS mode. See below for detailed explanations for each of the deployment modes. If you don't know what you're doing or do not understand the stuff here, we suggest you leave it on the default option. Bridge Mode (L2 Mode, Reporting and Blocking available)ĭefault mode is the second option: Routed (元 Mode) and with native netmap driver.Routed Mode (元 Mode, Reporting and Blocking available) Passive Mode (Reporting only, no blocking) Zenarmor can be deployed in three different deployment modes: You may reach the Zenarmor General configuration by navigating to Zenarmor -> Configuration -> General on OPNsense web GUI.
