I need a light Windows app just to forward a port to an external IP:port
Can you suggest a name of an app to do only this?

I'd do it via the router myself.

actually it can be done by the built-in firewall of windows. see below.

I don't have a router. Those software are for configuring routers to do so :(

I mean.... how can I set Windows to bounce external coming connections to port 443 to another external IP:443?
(in Windows)

I want to be able to redirect https://myPCip/........  to https://targetip/........

You would usually do this within a web server. So if you're running IIS on the IP you're mentioning, you could just use IIS to redirect that traffic. Otherwise, just install a lightweight web server like nginx.

Isn't there a lighter program that does only port forwarding for Windows?

You could try this: http://sourceforge.net/projects/pjs-passport/

However, note that the job of port forwarding is traditionally the job of a server of some sort or a router or firewall that is doing NAT translation, so do not be surprised at the lack of software for your exact situation. So the web server is for sure going to solve your problem, but there is a shot that link provided may be good enough as well.

masnrock: it seems exactly what I was searching for, however I set it to forward 127.0.0.1:443 to www.odesk.com:443 and pointing IE to https://localhost:443 I get a "The webpage cannot be found" response.

Service started successfully and I also completely disabled Windows Firewall.

Maybe it doesn't work on Windows 2008 Server?

That is possible... and is it actually forwarding properly? I'd be checking where it is redirecting to.

I see exactly why.... https://www.odesk.com:443 would fail, even if you try to go directly to it.... make the redirect go to http://www.odesk.com:443 ... that will work properly.

set your binding to www.odesk.com and add www.odesk.com to your hosts file

@David - IIS isn't being used, nor he is hosting a site of any sort.

How interesting that http://www.odesk.com:443 starts working again. It was failing at the time of my earlier post. So is your redirection now working correctly?

It's https, not http, and no, it never worked while it works if called directly after some seconds  :(

I set it to forward 127.0.0.1:443 to www.odesk.com:443 and pointing IE to https://localhost:443 I get a "The webpage cannot be found" response.

I'm totally confused, and it will FAIL because of a name mismatch,, http doesn't care but Https most certainly does as certificate will not match

If I set pjs-passport on my server PC to forward 127.0.0.1:443 to www.odesk.com:443 and point IE on my home client PC to https://localhost:443, I get a "The webpage cannot be found" response.

I should get the site www.odesk.com ignoring the certificate mismatch warning...

If I go to www.odesk.com:443 from my Firefox browser, the connection gets reset. If you change it to https://www.odesk.com:443 then things work successfully. So you need to do just that.

Using https://www.odesk.com:443 directly is exactly what I want to avoid,  because it would leave tracks of the site in the proxy logs.

This is why I want to point to a third IP, that forwards to oDesk.

Having it forward to www.odesk.com:80 would also work.

The issue seems to be the way that odesk's website works and redirects more than anything else. I can understand your reasons for frustration, but we do sadly enough have to feel out the terrain along the way with getting things to work.
