In FreeBSD, there is a built-in DNS server called Unbound.<\/p>\n
So why would run a local DNS server? I am in a region where internet traffic is still a bit expensive, that also implies slow, and high response times. To speed that a up a little, you can use own DNS server. It will speed up because for every homepage you visit, there will be several hooks to other domains: commercials, site components, and links to other sites. These, will now all be cached locally on your new DNS server. In my case I use an old PC-Engine Alix board for my home DNS server, but you can use almost everything, Raspberry Pi, old laptop\/desktop and others. As long as it runs FreeBSD.<\/p>\n
All commands run as root, or a user with sudo\/admin rights.
\nMy network router\/dns\/gateway: 192.168.1.1
\nMy new DNS server: 192.168.1.250
\nMy NIC on new DNS server: vr0<\/p>\n
sysrc ifconfig_vr0=\"inet 192.168.1.250 netmask 255.255.255.0\" \u00a0\r\nsysrc ifconfig_vr0=\"defaultrouter 192.168.1.1\" \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\r\necho \"nameserver 192.168.1.1\" > \/etc\/resolv.conf \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \r\necho \"nameserver 8.8.8.8\" >> \/etc\/resolv.conf \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\r\nservice netif restart \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \r\n\/etc\/rc.d\/routing restart<\/pre>\nNow lets install the unbound server. There is a built-in in FreeBSD callen local_unbound, but it is build for local only. While you can tweak it to work as LAN DNS, it is adviced to use the package unbound instead.<\/p>\n
pkg install unbound\r\n\r\nsysrc unbound_enable=\"YES\"\r\n\r\nservice unbound start<\/pre>\nDefault setting unbound only works for localhost, we need to change that setting:<\/p>\n
cat <<EOF> \/usr\/local\/etc\/unbound\/unbound.conf\r\n\r\nserver:\r\n\u00a0 \u00a0 \u00a0 username: unbound\r\n\u00a0 \u00a0 \u00a0 directory: \/usr\/local\/etc\/unbound\r\n\u00a0 \u00a0 \u00a0 chroot: \/usr\/local\/etc\/unbound\r\n\u00a0 \u00a0 \u00a0 auto-trust-anchor-file: \/usr\/local\/etc\/unbound\/root.key\r\n\u00a0 \u00a0 \u00a0 interface: 0.0.0.0\r\n\u00a0 \u00a0 \u00a0 access-control: 192.168.1.0\/24 allow\r\nforward-zone:\r\n\u00a0 \u00a0 \u00a0 name: .\r\n\u00a0 \u00a0 \u00a0 forward-addr: 192.168.1.1\r\n\u00a0 \u00a0 \u00a0 forward-addr: 8.8.8.8\r\nEOF<\/pre>\nNow lets set where our DNS server actually gets its DNS quires from:<\/p>\n
service unbound restart<\/pre>\nNow go point you device to your new DNS server!<\/p>\n
