Mixed network dynamic ip question

I have a linux client obtaining an address by DHCP, and a Windows box which may or may not have a static address.  These two boxes are separated across the Internet.   I need a way for the linux client to securely connect to the Windows box (ssh?) and update a settings file with the new IP address.  The Windows box will use this address to connect to the linux box.

Proprietary server                                                         Proprietary client

An odd problem, I know.  Why not just use dynamic DNS to update a DNS server on the Windows network, and use DNS?  The answer is that the Windows box runs a proprietary client program, with a static ip set in the client program's config file.  This static ip is supposed to be the linux box.  The program then connects to the static linux ip and downloads data.  This program does not give me the option to resolve DNS addresses.  Therefore, I'd like to update the config file either from the linux box, or a program running on the Windows box that updates the config file.

Is this possible?  If so, are there solutions out there that could do most of the work for me?

the ip on linux box is static?
if not,way can't you make it static ? (mybe with reservation  on dhcp server)
then you will get one IP to config in the config file.

The IP on the Linux box is dynamic.  I guess "just because" won't work for an answer.  :)

Part of the security requirements are that I use a dynamic IP address on the Linux side.

Commented:
you can use DNS and script that will ping to the dns and resolve the ip
and then set it into your config file.
you can do this with simple VBS that will run with schedule task.

OK, mybe didn't explain myself ...
do you know :www.no-ip.com ?
let say you register to this site, download the no-ip client for linux and install it on the linux box.
now you get DNS record that can be update every time the IP changed by the no-ip app.

for the windows side, you have small VBS that schedule to send ping with the DNS name
and resolve the IP.
the same VBS take the IP and put it in the config file.


now,if i'm not missing any thing,it mey work...
