You can see in the above screen shot that the DNS lookup request was handled by one of my domain controllers (redmond1 is the machine name) at IP address 192.168.10.4. Set the address of the Remote Gateway and a Description. If youre fortunate enough to have a static external IP address, DDNS will do nothing other than allow you to connect a domain name to your external IP address. Having your tunnel connect to their high end global network with over 200 data center worldwide is a bonus ;) WunderTech is a trade name of WunderTech, LLC. I will have to look for the settings you are using. That leaves maybe a firewall rule or DNS redirect on the firewall that is interfering with your AD server's DNS role. When using Active Directory, let it provide both DHCP and DNS services. You simply want CloudFare to identify and update its DNS with the public IP your firewall has at the moment. Your pfSense firewall comes with a DNS resolver binary out-of-the-box called unbound. I'm trying to install the Cloudflare application to build Argo Tunnels, namely "Cloudflared". To do that, open WARP's preferences, go to "Account" and click "Login with Cloudflare for Teams". You can, if you have a specific reason such as a desire to use an external DNS service for content filtering or some other unique setup, configure the DNS Resolver (unbound) to "forward" instead of "resolve via the DNS roots". Please download a browser that supports JavaScript, or enable it if it's disabled (i.e. Your desktops can then pick up GP from your AD, can get other devices on your network resolved from the AD DNS, and with your DC forwarding to PFSense, whatever you have there (Snort, PFBlocker, firewall rules) can then apply. When Cloudflare announced that their Tunnel service would become free, I saw an opportunity to strengthen the security of my Home Assistant instance. Was looking to make it run on pfSense. While I don't see the value (or even purpose) of moving application-specific tunnels to a general-purpose edge protection device, cloudflared does exist for FreeBSD. I got tired of having to do that over and over - so I turned OFF the AD DS server, and eventually deleted it (it was a VM). If I understood your original post correctly, when you had this set up the first time you had some things (maybe DHCP and DNS) happening over on pfSense. But usually that is not the case. It is critical that it provide DNS. It resolved the domain "cnn.com" to that list of IP addresses. That part is working. When you leave those IP address boxes empty under DNS Settings on the General Setup tab, then pfSense will automatically ask its internal DNS Resolver (that unbound executable I mentioned) to resolve IP addresses from domain names. As of right now - IPv6 is doing nothing (except this). Snort Make sure that your home network range isn't listed here. Then connect to the servers over Warp. How to set up Dynamic DNS via Cloudflare on pfSense First, log in to Cloudflare and choose DNS. Step 2: Install and authenticate Cloudflared on a Raspberry Pi 4: Cloudflared + Synology DSM - cannot upload larger file? 3. From Available network ports, select + Add. Now we want to install 1.1.1.1 onto the Android device. Disable the DHCP server on pfSense. It is key to have accurate and matching time across AD, so make sure everything points to the same NTP source. I'm trying it via the ports tree, but I get the following error message: Code: [Select] root@firewall:/usr/ports/net/cloudflared # make install ===> cloudflared-2020.11.11 License cloudflare needs confirmation, but BATCH is defined. You did not state initially state you wanted to use IPv6. I also want to setup a VPN at some point.will that be at the pfSense level too? pfsense starting dns resolver slow Cloudflare Tunnel has one more interesting feature I want to outline here: the ability to connect local web servers to their edge. Now I have stood up a new Server 2019 to be the DC. That request goes to your AD DNS server which sees the request is for a domain that it is not authoritative for. If not, it starts the resolving process described back up at the top of this reply. Since it is just a home network, I have not bothered. Currently the server has a static IPv4 address and is using pfSense as it's Gateway and DNS. 1 I would first get everything working with a baseline pfSense setup with regards to DNS. https://docs.freebsd.org/en/books/handbook/ports/#pkgng-intro. And if you want it to "forward", you must tell it the IP address of the Forwarder it should use. Change the Service Type to Cloudflare, then populate the Hostname section with your subdomain and domain name. We now need our Global API Key to use as our password in pfSense, which can be accessed in the API Tokens section of Cloudflare (My Profile > API Tokens). Some of your questions make it sound to me you are conflating these three when in fact they are quite different. You NEVER want to enable the DNS Forwarder on pfSense! In Windows, using the domain controller's DHCP and DNS services, this auto-registration works wonderfully. Do you have your AD DNS server's IP address being given out by the AD DHCP server as the DNS for clients to utilize? It might also help if you make sure you know the difference between "resolving" and "forwarding" when it comes to the operation of DNS servers. Much better to let the Microsoft servers handle all DHCP and DNS. Instead, this private connection is established by running a lightweight daemon, cloudflared, on your origin, which creates a secure, outbound-only connection. AD is very picky about DNS, and it puts some quirky Microsoft stuff in the zones. Update: I actually have some good news. Open a command prompt session on a Windows client on your LAN (use either a laptop or desktop PC). But I am sure I had something wrong when I set it all up before - as basically before setting up pfSense (my NETGEAR ORBI was my DNS, my DHCP and my FIREWALL). You can, of course, let pfSense be the DHCPv6 server (or use something like SLAAC). I configured a tunnel on my Rasp Pi server but ultimely moving the tunnel to pfSense would be preferable. Hosting a VPN server at home means your connection becomes as slow as your home's upload speed, which is usually very slow. Cloudflare Tunnel - Cloudflare Tunnel - IBRACORP If you configure the DNS Resolver in pfSense for forwarding, then "yes" you will want the forwarder's IP address in the SETTINGS > GENERAL SETUP tab of pfSense.

What are those there for? Do you have some screen shots of your pfSense and AD DS setup (you can blank your IPs - etc.)? I am willing to reload pfSense back to Factory Defaults if I can get this working - I just do not want to lose Internet in 7-10 days - one day happened while I was on a SEV-1 Customer Call - That was hard to explainwhen I disappeared for 15 minutes when I rebooted everything. Head over the Teams dashboard > Settings > Devices > Device enrollment and click on "Manage": Here you can create a rule that only allows people with a certain email address to access your Cloudflare Team and the tunnels assigned to it.

From $5/mo with Free Plan. @bmeeks said in pfSense with CloudFlare (and WireGuard - soon) - setup AD DS: Edit: after re-reading your post, most definitely YES, remove those Cloudfare IP addresses from the GENERAL SETUP page. Watch the video with the NEW method, deploying the CF tunnel from the GUI: https://youtu.be/c4P31IhYx9Y 0:00 Intro. Cloudflare WARP utilizes WireGuard VPN protocol for easy, modern, simple, fast as well as secure VPN implementation. If IPv6 is available, Windows will default to using it first. In the case of Cloudflare Zero Trust (Tunnel, Argo, cloudflared), there is great control of who (user), what (device management), and where (endpoint) is allowed. As a result, your viewing experience will be diminished, and you have been placed in read-only mode. I did it mainly for my HomeAssistant (SmartHome) - I have a sub-domain setup there, which filters traffic from outside my home - to the HomeAssistant server. For this step, you don't need to go beyond signing up. Under Interface, select OPT1. Argo Tunnel creates a secure, outbound-only connection between your services and Cloudflare by deploying a lightweight connector in your environment. Do you have DNS redirects in place? As for DNS, you can import the DNS roots and let the AD DNS server resolve, or you can leave pfSense at its default setup and tell the AD DNS server to forward zones for which it is not authoritative to pfSense.

Please download a browser that supports JavaScript, or enable it if it's disabled (i.e. (I gave up on IPv6 - would get it working, only to have it stop in 5-9 days). Obviously make the NTP stuff in pfSense is set up correctly. In home networks, the best thing in my opinion is to install two domain controllers as virtual machines, and then add the DHCP and DNS feature to both of them as part of the AD setup. So I switched it back (pfSense does everything). Cloudflare doesn't seem to be passing traffic to pfSense You do that by checking the "Use Forwarding" box and then (and only then) putting the IP address of the DNS forwarding server you want unbound to ask for IP addresses. That is NOT where those would go. IPv6 on your LAN To expose a local web service, edit your config.yml file and add an ingress section: Finally, create a CNAME record in your DNS settings that points towards your tunnel: You can create as many ingress rules as you want. This is for my home where I have my own Cable Modem >> pfSense >> ORBI (in AP mode) for WiFi and everything else is wired. This topic has been deleted.
