Hi everyone,
I have a public domain name with a public ip address that redirect to an internal server in my LAN for external access.
- Domain name : momohib.domain.com
- Public ip address : 81.276.XX.XX
i configured DNS resolution in my cisco router isr4321 to resolv the same domain name locally in my LAN.
momohib.domain.com ---------------------> 192.168.10.20
My configuration :
ip domain name domain.com
ip host domain.com ns routeur-dns.domain.com
ip host routeur-dns.domain.com 192.168.20.1
ip host momohib.domain.com 192.168.10.20
ip dhcp pool LAN
network 192.168.20.0 255.255.255.0
default-router 192.168.20.1
dns-server 192.168.20.1 192.168.1.1
when i do nslookup momohib.domain.com
Server: 127.0.1.1
Address: 127.0.1.1#53
Non-authoritative answer:
Name: momohib.domain.com
Address: 81.276.XX.XX
I'm always on the public ip address . how can i please resolv the public domain name locally ?
thank you

Hello,
configure the below globally:

ip dns spoofing

I think you are missing the commands
R1(config)# ip dns server
R1(config)# ip domain-lookup
so your local router does not really act as dns server that respond to dns requests,
your answer may come from another cached data or from 192.168.1.1
