Dynamic DNS and website development

I have a dynamic IP address, this changes every day or so depending
on when my ADSL router has to reconnect.

I have a hostname from dyndns services that is updated to point to my
changing IP address when required.

I have a website on my internal network that is accessible from the Internet
using the dynamic hostname.

When I am testing things on the website from my internal network I use the IP
address from my internal network or the hostname from my internal network
which is different from the IP address and host names seen from the Internet.

Most of the stuff on my website does not need to refer to the the full address
like; http://host.domain.org/dir/file.html but some do. How can I use the
external address like host.domain.org from the internal network?

Do I have to change the hostname on my internal network?
Do I set something in my httpd.conf file?
Do I set something in my own dns server?

Thanks alot,

Adrian

Easiest is to put private IP and public name in hosts file of client.
Then you could access public name of server from private LAN via private
IP, but public would still be able to access it by public DNS IP.

I actually have wildcard NameVirtualHost * for multiple public dynamic DNS
names (no-ip.com) and a default nameless vhost to log worms. So I can
locally access public content by mapping my public name to private IP in
/etc/hosts, and private content by mapping a private name to that IP with
local DNS. That way I can still lookup the public IP for my public name
using 'host' (or nslookup), which always uses DNS.

You could simply add an emtry to /etc/hosts with your dyndns pointing to
your internal ip.

Asumming your dynamic dns is dynamic.dyndns.org, external ip to be anything,
internal ip 192.168.0.10.

% cat /etc/hosts

127.0.0.1 localhost.localdomain localhost
192.168.0.10 dynamic.dyndns.org dynamic

With this (if properly setup), by default should return 192.168.0.10
whenever your machine is looking for dynamic.dyndns.org, while external
machines will access dynamic.dyndns.org with your dynamic IP.

Hope this helps.

Thanks for all the replies. I have tried the modification to
/etc/hosts and this works fine.

127.0.0.1 localhost
127.0.2.3 localhost.localdoamin
10.0.0.4 blab.internal.org ahost
10.0.0.4 dynamic.dyndns.org
