Ben,
Ok, maybe I'm misunderstanding you.
Why would I need to be port forwarding?
All my relevant hosts and my DNS server all sit on the 192.168 subnet
all behind the same firewall with no reason to go near the modem? The
DNS server does act as a firewall, but yes, the relevant ports on the
eth1 side for DNS are open (namely 53 & for whatever reason - can't
remember now - 953).
For clarification the setup is
modem (FW)
|
Server (FW, DNS, DHCP, etc) eth0 = 10.X subnet eth1 = 192.168
subnet DHCP listens on 192.168.x.x
|
internal DHCP hosts on 192.168 subnet

Kind Regards

yes that's what I'm talking about.
are you port forwarding DNS to your internal dns server?
setup a test box on the inside of the modem and see if it works with
just the modem in place.
Thanks,

Ben,
thanks for taking the time to look. Perhaps I wasn't clear. My issues
are not external clients not updating; rather internal only. I.e.
Everything behind my firewalls.

Hi,
I'd check that you are port forwarding or "virtual server" from the
modem port 53 tcp and udp to the internal dns server
reboot everything starting from the modem and working your way inwards
try to simplify the problem. Run up a new box if you can and stick
it temporarily on the inside of the modem and see if it is getting
dns correctly... go to websites etc.... if working then place it on
the other side of the svr1 and test from there...
Thanks,

Hi SLUG,
I have an issue that is becoming more annoying the more I try to
track it down.
Can I ask those of you interested to take a look at the following
thread please:
https://www.centos.org/modules/newbb/viewtopic.php?topic_id=30080&forum=40
I realise this might be a little .... brave ... to ask you to go
outside the list, but it is a fairly detailed thread (i.e. lengthy
read) with all the necessary info on the box's config and all the
testing I have done.
In short;
-----------
mixed clients XP, 7, OSX, Ubuntu 10 to a CentOS 5.5 svr all in an
MS WORKGROUP type setup.
DHCP licences handed out, some reserved.
DNS zones supposedly set up to provide name-based network browsing
within the WORKGROUP domain and for internal clients to find
inbound mail servers for 5 other domains.
-----------
But try as I might, I can't seem to get the DNS updated anymore and
I swear it USED TO WORK. The only thing I have since done is update
the packages as they came out.
I am as far as the error: "Unable to add forward map from
client1.domain1.com to 192.168.1.104: not authorized" and that's
where it stops. No amount of googlage has so far shone a torch on
the issue. The disheartening thing is the bloody redmond boxes CAN
find other hosts by name, but not the linux or OSX boxes.
If you have the time and incl. to have a read and point out where
the hell I'm going wrong pls, I'd be grateful.
