ZoneEditor 1.0.1
================

ZoneEditor is a Windows service that periodically checks for changes in a 
host's IP address and updates DNS records with the ZoneEdit dynamic DNS 
service. It is written in C# under the .NET framework and offers plug-in 
support for various routers.

Motivations
===========

The idea for ZoneEditor appeared when I switched the router/firewall on my 
home network from a FreeBSD system to a ZyXEL ZyWALL 10 hardware firewall. 
While previously, shell scripts tied to DHCP changes successfully managed 
DNS updates with ZoneEdit, no such functionality existed on the ZyWALL. 
Thus, the need for an external monitoring utility became apparent. A 
Windows service performing periodic checks on the external IP through the 
firewall's telnet service seemed to fit the bill quite well.

Usage
=====

After the installation, edit the ZoneEditor.exe.config file with your 
ZoneEdit and router/firewall credentials, DNS records to update and poll
interval for checking IP changes. Once you have completed the set-up, open
the Services console and start the ZoneEditor service. By default, the 
service is set to manual startup. To uninstall the service, simply choose
Remove from the Add/Remove Programs applet in the Control Panel.

Plug-ins
========

ZoneEditor implements router/firewall device connectivity through plug-ins. 
The ZyWALL plug-in ships with the standard installer, since this is the 
device used in developing and testing the service. To install a new plug-in, 
simply drop the plug-in DLL into the ZoneEditor installation folder, change 
the appropriate entry in the ZoneEditor.exe.config file and restart the 
service. From a developer's perspective, a plug-in is a library that 
implements the IFirewallConnector interface as the FirewallConnector class. 
Once the library is made visible to ZoneEditor, it is automatically loaded 
on service start.
