Upstream DNS over TLS

[Peter Fraser]

Never mind. I figured it out. It seems something was wrong with my cert bundle. Works perfectly now.


Best Regards and thanks.

Hi All,
I have migrated my two Bind Servers to NSD and Unbound on FreeBSD 13.1. Works very well and is very fast. My last task is to configure DNS over TLS for only external queries. I want to have unbound accept udp queries on port 53 as usual internally, but use DOT when it queries external upstream servers. So far, I have managed to get the DOT queries working upstream but the local clients can no long use the servers. The configs I tried are below. Any help would be apreciated.

server:
tls-cert-bundle: "/usr/local/etc/ssl/gd_bundle-g2-g1.pem"

forward-zone:
        name: "."
        forward-tls-upstream: yes
        forward-addr: 1.1.1.1 at 853    #one.one.one.one
        forward-addr: 8.8.8.8 at 853    #dns.google
        forward-addr: 8.8.4.4 at 853        #dns.google
        forward-addr: 9.9.9.9 at 853    #dns.quad9.net
        forward-addr: 1.0.0.1 at 853    #one.one.one.one
        forward-addr: 149.112.112.112   #dns.quad9.net

Then I tried
server:
tls-cert-bundle: "/usr/local/etc/ssl/gd_bundle-g2-g1.pem"
tls-upstream: yes

forward-zone:
        name: "."
        forward-addr: 1.1.1.1 at 853    #one.one.one.one
        forward-addr: 8.8.8.8 at 853    #dns.google
        forward-addr: 8.8.4.4 at 853        #dns.google
        forward-addr: 9.9.9.9 at 853    #dns.quad9.net
        forward-addr: 1.0.0.1 at 853    #one.one.one.one
        forward-addr: 149.112.112.112   #dns.quad9.net
