For me, the list is called bind-users, not bind-discussion. BIND discussion would be a higher echelon than a user list. I'm a bind user and I have a Domain Name Server problem, somewhere, that I have been trying to solve for a long time and am going over my steps once again. I need to get my webserver online and there is a problem with the name or lookup or the router. I have not found any errors in httpd, bind or the router configuration that have solved it. The latest hint I got was an ostensible missing in-addr.arpa PTR record, which, to me, made it relevant to BIND.

If so, you will need to enable static port forwarding for 80/tcp to the VM running the webserver, or perhaps place that IP in the router's "Enable DMZ Host" section of the firewall config.

The ports forwarded to the 192.168.0.101 webserver are unchanged since 2005; dns, http and ssh to appropriate ports. The router did change, the static ips changed, as well as the physical location of the network and servers. I don't know what the issue is, that's why I asked about including explicit PTR files to the domain name, as well as the localhost in-addr.arpa, which is the latest in a list of "possible irregularities" I have turned up so far that I need to confirm one way or the other.

I do appreciate you taking valuable time to answer. I have to wade into it all again. I hope I am still welcome to ask questions here as I have seen others do, since I subscribed to this list in an effort to learn about BIND and DNS, a number of years ago.
