Can ping IP, but cannot ping hostname
I set-up a test server with NAT, so access will be on the interface to be treated as public but it's still a private IP.
172.16.100.100 <--> 192.168.100.100, where in 172.16.100.100 is defined in eth1, while 192.168.100.100 was defined in eth0.
192.168.100.100 cannot be accessed directly. All devs/support must ssh to 172.16.100.100.
Then from 192.168.100.100, we can ping the IP 10.10.100.100 (prodserver.prod.local), but if we ping the hostname it doesnt pass. If we do nslookup for 10.10.100.100, it can be resolved. Our temporary solution is to put it in /etc/hosts. We cant do it, since we'll be placing at least 50 servers on this segment, that's why we placed it on the DNS.
Any though guys?
