CentOS 5, Zimbra, DNS problem.
I'm setting up Zimbra Open source mail server, which I can pretty much do myself with no problem except that when it tries to do a nslookup for my domain "rebelfighter.no-ip.com", which resolves to my external ip, it tells me that the domain doesn't point to my internal ip which is 192.168.0.131.
yes I know that its a sub-domain but its free. Could this be the problem?
I think the only way to get around this is to set up a internal DNS server or a split DNS to service request from the outside.
I've been trying all sunday afternoon and night to get this work.
I've been using this guide from howtoforge.com
Resolving Domains Internally And Externally With Bind9 And Caching Nameserver | HowtoForge - Linux Howtos and Tutorials
I also been using the zimbra wiki to set up a split dns.
Split DNS - Zimbra :: Wiki
and this centOS guide,
Chapter¬*16.¬*Berkeley Internet Name Domain (BIND)
and few other guides/sites to help me.
I can't get it to work.
when I do nslookup for server.rebelfighter.no-ip.com
It always comesback with the error "server can't find server.rebelfighter.no-ip.com NXDomain" or something to that extent.
when I do nslookup rebelfighter.no-ip.com it points to my external ip.
I'm not sure what I'm doing wrong, or have a clue what I'm doing with DNS configs.
I've wiped and reload my testbed system to start from scratch again.
zimbra and DNS/BIND willl be running on the same machine.
Firewall, selinux disabled on the machine because I sit behind a router/firewall.
Router port forwarding already setup and is working properly.
Domain is rebelfighter.no-ip.com
local ip 192.168.0.131
How should I setup my dns?
How should I fill out the configs? named.conf, rebelfighter.no-ip.com.zone resolv.conf.
Any Help appreciated.
