Hi, I'm running Unbound (for the very first time - so please bear with me) on a router with three interfaces.
The 1st interface is PPP to my ADSL modem and has an Internet IP address 51.x.y.z. I have global DNS pointing 'nimbus.my.domain.uk' to this address. The 2nd interfac is WiFi with a private IP address of 192.168.1.1 The 3rd interface is an Ethernet connection to my office and has another private IP address of 172.28.1.1. Routing is configured to send 172.28.0.0/16 through this interface, and have a few services in this network, including a service which I want to be accessible from both internal and the Internet. I'm trying to get the Unbound to provide a private IP address to a global Internet DNS name with: local-data: "nimbus.my.domain.uk. IN A 172.28.4.30" When I use 'dig', I get confusing results. For all interfaces other than the 3rd: dig @<interface IP> -p 1053 nimbus.my.domain.uk returns 172.28.4.30 However, for the 3rd interface, it returns the Internet IP 51.x.y.z which is being resolved by the global Internet DNS. Why? I can't see any configuration option that would cause this. I can't see this being an RFC1918 issue as 192.168.1.1 works, while the other RFC1918 address fails. At the same time the 51.x.y.z Internet address also works - there doesn't seem to be a pattern! Note that I'm using a port of 1053 only while I'm testing. While I'm sure I couls point all resolvers at 192.168.1.1 as a workaround, the fact that I can't figure this out means I'm missing something. I'd rather get to the bottom of this before I continue. Thanks, Gareth
