![]() This allows it to be installed usingĪpt-get install nodered and includes the Raspberry Pi OS-packaged version Please see your distribution's documentation for the exact proper command to use.Node-RED has also been packaged for the Raspberry Pi OS repositories and appears in their Note: These examples insert the rules at the front of the chain. Full Stack ( IPv4 and IPv6) require both sets of rules to be applied. If only IPv4 blocking is used for the Pi-hole installation, only apply the rules for IP4Tables. ![]() One set is for IPv4 chains, and the second is for IPv6 chains. 192.168.0.0/16 is the most common local network IP range for home users but it can be different in your case, for example other common local network IPs are 10.0.0.0/8 and 172.16.0.0/12.Ĭheck your local network settings before applying these rules. These are only shown as guides, the actual commands used will be found with your distribution's documentation.īecause Pi-hole was designed to work inside a local network, the following rules will block the traffic from the Internet for security reasons. Firewalls ¶īelow are some examples of firewall rules that will need to be set on your Pi-hole server in order to use the functions available. The use of pihole- FTL on ports 67 or 547 is optional, but required if you use the DHCP functions of Pi-hole. The use of lighttpd on port 80 is optional if you decide not to install the Web dashboard during installation. This port should not be accessible from any other interface. You can either disable the other Web server or change the port on which lighttpd listens, which allows you keep both Web servers running.įTL is our API engine and uses port 4711 on the localhost interface. If you have another Web server already running, such as Apache, Pi-hole's Web server will not work. The DHCP server is an optional feature that requires additional ports. If you happen to have another DNS server running, such as BIND, you will need to turn it off in order for Pi-hole to respond to DNS queries. This is an entirely optional step, and offered as a way to lower the barrier to entry for those that may not be familiar with linux systems, such as those first starting out on a Raspberry Pi. On systems that have dhcpcd5 already installed (e.g Raspberry Pi OS) there is an option in the install process to append some lines to /etc/nf in order to statically assign an IP address. Pi-hole needs a static IP address to properly function (a DHCP reservation is just fine). If you choose to use this environment variable, please use the Community Help topic on Discourse to troubleshoot any installation issues you may (or may not!) have. You can disable this check by setting an environment variable named PIHOLE_SKIP_OS_CHECK to true, however Pi-hole may have issues installing. ![]() If that is the case, you can feel free to ask the community on Discourse with the Community Help category: (In this case, your previous run of pihole -up will have already updated the local repository ) It is possible that the installation will still fail at this stage due to an unsupported configuration. Sudo PIHOLE_SKIP_OS_CHECK = true pihole -r If you are seeing this message after having run pihole -up: If you wish to attempt to continue anyway, you can try one of the following commands to skip this check:Į.g: If you are seeing this message on a fresh install, you can run:Ĭurl -sSL | sudo PIHOLE_SKIP_OS_CHECK = true bash Unsupported OS detected: Debian 16 If you are seeing this message and you do have a supported OS, please contact support. Optional: Dual operation: LAN & VPN at the same time
