5. Pdns-recursor.

5.1 Principle.

Pdns does not allow redirection for other domains.
I am using pdns-recursor to do the redirect.
Operation:
Pdns-recursor responds to all dns requests on port 53.
If these requests concern the ol26modk.com domain , pdns-recursor redirects these requests on port 8669 to pdns.
For other domains pdns-recursor redirects these requests to another dns server.

5.2 Installation.

dnf install pdns-recursor

5.3 Pdns.

pdns configuration to listen on port 8669.
vi /etc/pdns/pdns.conf

# local-address Local IP addresses to which we bind  
local-address=0.0.0.0  
# local-port    The port on which we listen  
local-port=8669  

systemctl restart pdns
systemctl enable --now pdns-recursor

5.4 Pdns-recursor.

vi /etc/pdns-recursor/recursor.conf
Please put the redirects of areas managed by their servers.

# forward-zones Zones for which we forward queries, comma separated domain=ip pairs  
forward-zones=ol26modk.com=127.0.0.1:8669, 50.168.192.in-addr.arpa=127.0.0.1:8669, 90.168.192.in-addr.arpa=127.0.0.1:8669  
## If you have AD domain server.  
forward-zones +=dw.learn.lan=192.168.40.47:53  

Put the redirection dns server (here 1.1.1.1).

# forward-zones-recurse Zones for which we forward queries with recursion bit, comma  
forward-zones-recurse=.=1.1.1.1  

Put the IP of the DNS server.

# local-address IP addresses to listen on, separated by spaces or commas.#  
local-address=192.168.90.41  

Pdns-recursor listening port 53.

# local-port   port to listen on  
local-port=53  

systemctl restart pdns-recursor

5.5 Network.

Put the ip of your DNS server.
nmcli con mod eth0 ipv4.dns 192.168.90.41

systemctl restart NetworkManager
cat /etc/resolv.conf

search ol26modk.com
