Hello Himba,
From: himba [mailto:himba@siol.net] Hello I would like to run DNS server inside the local LAN (behind router/firewall), on Suse8.2. I have bought domain name, and configured bind9 that came with Suse8.2. Domain admin company for my country -Slovenia- has web based tool for checking DNS server configuration online. When I do check for my domain, with my DNS server as primary, web tool is capable to get SOA record from my DNS server, later it tries to check SOA records' config values and it timeouts while trying to contact my server. I noticed that in the begining of test, web tool uses public IP address of my DNS server (193.x.x.x) to access zone files, later in test, it tries to contact my DNS server using it's private IP address (192.168.0.69) and it can't get no answer - timeout?!
You have to configure your DNS with an official IP address, because the NS-records in the zone-files are important for the name resolution and Internal addresses are not routed via the internet.
On router I opened both 53 ports (udp, tcp) towards DNS server inside LAN. I have read short description, about DNS server config, found in suselinux-adminguide_en.
Additionally you have to open high ports (1024-65535). There is a very good book for DNS-beginners, it's called "DNS and BIND" by Albitz and Liu: http://www.oreilly.com/catalog/dns4/
What am I doing wrong :)?
regards, himba
Good luck :o) Stefan
