Hello. I connect to the internet via a cutdown firewalled O/S RedHat
I am running as primaryDNS on an internal RH machine for my hostname. From an internal windows machine I can ping all machines IP addresses but not their names.
I have set up a host file on my linux-firewall in /etc/hosts with all aliases for machine (
www.domainname.com webmail.domainname.com etc) From my windows machine when I ping one of these sometimes it will reply from my LAN IP 192.168.0.* & sometimes it will reply from my actual net IP provided by my ISP. Why Is this ?. I am wanting to be able to ping all machine names & get a reply & also when pinging any subdomains i have setup i want these to ping via their internal IP. Only when i am outside my network do i want these to ping my external IP.
Hope you can Help
Regards
Andrew
