config a web server with dyndns behind a router

I want to be able to use my PC as a web server.
It's running Win Server 2003, has DynDNS running, and is behind a D-Link wireless router.

I thought I had tried everything I know - but if I get a page at all, it's the router admin page and i'm getting a bit frustrated. Could someone provide an idiot's guide please?

I can supply more info if needed...

tleighton999 is right, you need to check that you can get to your router from the Internet.  You have not said if you were able to do that (being able to get there from your LAN is not the issue, I assume).

If you can, then you need to see if the router passes requests through to your Web server machine.  You have not confirmed whether that is the case, either, although you hinted that an external request gets to the router rather than your Web server.

If an external request gets your router, then follow tleighton999's suggestion to check that your router is truly forwarding requests rather than doing a loopback (which means it is responding to requests rather than forwarding them to the server behind the router).

If you don't understand how to check that, then you can look up support for your brand of router (or check the help files with it) and it will tell you what the loopback feature is, and how to turn it on and off.

You have not yet responded with an answer as to whether the page you are trying to get from your Web server is a plain html file or whether it is a CGI or application page of some sort.  If you are using a webcam, then it might be cgi, and you will have further issues with IIS configuration before it will work.
What URL are you trying?  Is the Web server available to the Internet, or only within your LAN (or Intranet)?

Which Web server are you using -- IIS?

Have you set the router to port forward traffic on ports 80 and 443 to your Servers IP address?

One of a set of tools we are providing to everyone as a way of saying thank you for being a part of the community.

I see -- the groups for the questions don't all display.  So you are using IIS but it isn't available to the Internet?

What page are you trying to display -- is it a basic index.htm?  Or is it an ASPX or CGI page?  If the latter, then you have to turn on that capability in IIS before it will serve the page.

But the fact that you're getting the router implies that you haven't correctly opened the port on the router or the port on the Win2k3 server.
Sorry waskdi -- didn't see your post before either of mine.

Your problem may be because of a loopback issue on your router, mine has one, and to check if my sites work i need to use a website such as

If it works externally, then i cant think of a fix for your router, but other people should be able to access it if the ports are forwarded correctly.

hi all

i have ports 80 and 443 forwarded to my server
i know that it's possible with my router, because an ex-colleague used to have a webcam hooked up, and used DynDns and some webcam prog to broadcast live images on the internet - using same router model.

As said, if the sites work using then there is a local loopback issue on your router, it is common if it is not a business class router.
