One of Firewalla's major functions is managing your network traffic through features like Rules, Routes, and Smart Queue. These features require selecting a "target" and applying an action to a device, a group, or a network segment. Currently, to specify a target, the system only allows one IP/IP segment or one top-level domain. This can result in needing to make several rules if you have more than one target in mind. Many of you suggested we should use a list instead.
Introducing Target List
A Target List is a set of targets defined by domain (exact or all subdomains) or IP (exact or range), which can be used as a building block to create rules or prioritize a group of targets. If you have a lot of rules, this feature can help you to organize them.
The Firewalla Target List feature allows you to:
- Create your own Target List to simplify rules.
- Use an existing pre-created list.
Target Lists can be used with the following features:
- Rules: control access, content filtering
- Smart Queue: regulate traffic flow
- Policy & Content-based Routing: route of network traffic
- Alarms: mute alarms based on a Target List
Target List Definition:
- Target Lists can only be created and managed using the Firewalla Web interface
- Rules using Target Lists can be created/managed via the Firewalla Web or App
- Target List items for this version are restricted to 200 items
- Target List elements can have the following forms:
- Exact-match IP: e.g. 220.127.116.11
- IP Range in CIDR notation: e.g. 192.168.0.1/24
- Exact-match domain: e.g. firewalla.com
- Match-all subdomains: e.g. *.firewalla.com
(We ONLY support the exact form of a single '*.' before the domain name)
- You can only create up to 20 Target Lists
- Target Lists are not available on Firewalla Red
Create Target List on Firewalla Web
Login to Firewalla Web, click Target List on the left side, and you'll see a list of pre-built target Lists owned by Firewalla.
Built-in Target Lists
Firewalla maintains these list items. You can use them wherever Target Lists are accepted (Rules, Smart Queue, Routes, Alarm muting). Their definitions are proprietary.
|Apple Private Relay||
Apple's iCloud Private Relay feature encrypts DNS requests. However, using it may mean that Firewalla has less information about network traffic, and some of your policies may not work as intended. This Target List blocks Apple's Private Relay Servers, banning their relay service and returning complete visibility to your Firewalla.
This Target List consists of known cryptocurrency mining sites and can be used to block cryptocurrency activities.
DShield Block List
DShield.org is a collaborative cyber threat logging system. We recommend that you block this list.
|DoH Services (beta)||
This is a list of well-known DNS-over-HTTPS (DoH) servers. Some browsers have built-in DoH services that encrypt DNS requests, which may get in the way of your rules and policies. You can block this list to prevent browser-based DoH from working and ensure that your rules will function as expected.
|Tor Exit Nodes||
A Tor exit node is the gateway between Tor encrypted traffic and the Internet. Blocking this list will block just these Tor nodes.
|Tor Full Nodes||
This list is of all Tor nodes. Be aware that this list is not just exit nodes.
This is a list of known log4j attackers from a public list.
Create your Target Lists
To create your own, click the Create Target List button in the top right corner.
Security example: Here is an example of creating a Target List to identify the malware command and control sites associated with, "Purple Fox."
Parental Control Example: You can create lists of specific sites like "Gaming" for kids.
Update a Target List
In addition to the web interface, on the Firewalla app, we've supported the ability to quickly add a domain or an IP address from a flow or an alarm to a Target List you've created.
For example, if you already have a rule that blocks a list of targets, adding a new domain to the Target List will automatically be updated to block the new target.
Create Rules/Smart Queue/Routes using a Target List
On the Firewalla app and web interface, you can create a rule, a Smart Queue rule, or a policy-based route matched to a Target List.
You can view the detail of the Target List on the Firewalla App by tapping the "i" icon on the right side of any Target List.
Example: Block iCloud Private Relay using pre-defined Target Lists
Apple iCloud Private Relay is one of the most exciting features in iOS 15 and macOS Monterey. It will encrypt and obfuscate your source IP address to protect your privacy while using Safari. This is perfect if you're using free Wi-Fi in a cafe or a store and want to protect your privacy.
Unfortunately, this encryption will also block devices like Firewalla from operating on the network to filter and audit traffic.
Besides turning off iCloud Private Relay directly on your Apple devices, Firewalla can disable this feature on your network by creating a BLOCK rule using the pre-defined Firewalla Target List called, "Apple Private Relay."
To create the Rule, go to Rules -> Add Rule -> set the target to Target List" Apple Private Relay" -> apply to any device -> Save.
You can also block a list of IPs or domains from accessing a certain port on your local devices by creating a rule matching a specific Local Port and a Target list.
Example: Prioritize traffic for online meetings
In addition to Firewalla's built-in Apps, you can create a Target List and put all the sites you and your company use for online meetings, then create a smart queue rule to prioritize the meeting traffic using the Target List.
- Smart Queue -> Smart Queue rules -> Add Smart Queue Rule
- Set a target -> Target List -> Online Meeting
- Apply it to any devices/network you might use for online meetings.
- Set the Priority to High.
- Save the rule.
Example: Route your Netflix traffic to a particular VPN
If you want all the Netflix traffic on your Apple TV to go to a 3rd party VPN, you can create a Target List with the primary domains Netflix is using, then create a policy-based routing rule using the Target List.
- Routes -> Add Route
- Set a target -> Target List -> Netflix video
- Select a device -> MyMac
- Select an interface -> 3rd party VPN
- Save the Route
Example: Mute Alarms based on a Target List
If you want to mute alarms from a list of IPs used by Ring services but don't want to create mute settings for each IP individually, you can create a Target List of those IPs and selectively mute alarms related to those IPs. Create your Target List, then configure your alarm settings.
- Alarms -> Alarm Settings
- Choose an alarm category -> Mute
- Tap Add Target List and select the Target List you created
- Apply the mute setting to the devices you want to mute the alarm for.
Do I need to import a security list for better security?
You do not have to. Behind Firewalla, an extensive list of security intel is already integrated with your box. This list is part of our Firewalla security intel. Please see https://help.firewalla.com/hc/en-us/articles/360049856394-How-to-Secure-Your-Network-with-Firewalla-Part-3-Protect
Since Firewalla's security intel is dynamic and actively managed, if you ever need an on/off switch in a list form that's part of your team/work/home policy, you can integrate it with the Target List.
Can I create and manage Target List on the phone?
No, you can't; managing lists is a web-only function. Managing lists is a complex process, and mistakes can take time to debug.
Can I add to a Target list from Flows or Alarms?
Yes. When you tap on a domain in a Flow or Alarm you can add a domain or IP to an existing Target list.
I have a list that I think is good, can you integrate it?
Yes, please send your list to firstname.lastname@example.org
We can only integrate some of the lists out there. Not all lists are equal– some are well-maintained, and some need a lot of work.
Why is the Target List limited to 200 elements?
The manual input lists are there for specific usage. For more extensive lists, it needs to be filtered and cleaned by the software and then imported. This means a cut/paste of a large list may work in a day or two. Without updating it, it may stop working a month out. If you would like to create Target Lists with more items, check out Firewalla MSP, our tool designed for security and infosec professionals to easily manage multiple Firewalla boxes remotely. Through Firewalla MSP, you can create Target Lists with up to 2000 elements.
