zHi Team
Ive got a number of hosts on my lan that I need to reference using domain names in applications.
Those applications are used internally and externally, so whilst NAT NVI helps it stuffs up aload of other things on my network so i figure use DNS.
When on the LAN, my hosts cant ping the dns names.
Heres my config, ip domain lookup is on
ip domain name ddns.net
ip host doorbird 192.168.0.141
ip host grafana80 192.168.0.3
ip host oh2 192.168.0.3
ip host dastrix80 192.168.0.3
ip host blueiris 192.168.0.4
!
ip dns server
In my external DNS server, I reference the same names (doorbird.ddns.net) with my PUBLIC IP.
Internally though, having my clients set to the router LAN IP as their Primary DNS, I cant ping the names.
C:\Users\Kris>ping doorbird
Ping request could not find host doorbird. Please check the name and try again.
C:\Users\Kris>ping blueiris
Ping request could not find host blueiris. Please check the name and try again.

Any thoughts as to why?
