Unbound IP redirection

Question

I'm trying to redirect my LAN queries i.e. 10.0.0.0/8 to my captive portal hosted at 10.10.10.10.

I've 2 networks, 10.0.0.0/8 and 192.168.1.0/24. Objective is redirect 10.0.0.0/8 to 10.10.10.10

There's no DHCP server at the moment for this IP Pool, devices are statically mapped with 10.x.x.x/8. All DNS queries are going to Unbound resolver.

I tried creating a few changes in the unbound-config but no luck so far.

Server: <Additional 3 lines below>

unblock-lan-zones: yes

insecure-lan-zones: yes

domain-insecure: "10.in-addr.arpa."

Option 1: local-zone

local-zone: "10.in-addr.arpa." transparent

forward-zone:

name: "10.in-addr.arpa."

        forward-addr: 10.10.10.10

Option 2: via define tags

define-tags: "portal" access-control-tag: 10.0.0.0/8 "portal"

access-control-tag-action: 10.0.0.0/8 "portal" redirect

access-control-tag-data: 10.0.0.0/8 "portal" "A 10.10.10.10"

Option 3: Respip module

response-ip: 10.0.0.0/8 redirect

response-ip-data: 10.0.0.0/8 A 10.10.10.10

Can you please steer in the right direction?

What do you mean by "_LAN queries_"? All of them regardless of destination? Or just queries for off-site addresses? — roaima, May 09 '22 at 06:56
Please take a look at formatting with `{}`. You can use it for blocks of configuration too — roaima, May 09 '22 at 06:58

OK. Please add that to your question. To redirect DNS queries? If so, DNS queries from hosts on your LAN? Why not just fix the DNS servers given out through DHCP? — roaima, May 09 '22 at 15:54
