Web Service issues - DOTNET

And while I am not sure it matters, here is the rest of the stack:

- VS 2006
- CF 2.0
- ActiveSync 4.5

Well, I think it works while debugging, because the connection you have
there is already in the internal network (somebody correct me if >I am
wrong).

All I can say is that I had the same problems with reaching an IIS
Server (on my Home PC behind a router) from outside. If i called the
server from network it did work out and i think same is happening to you.

Did test different settings (IIS and Router), nothing worked out,
something is wrong.

What you are saying is trivial, but
- I cannot be hitting the server through the inside network, because it does
not listen on port 8080. I must be coming in via the Edge network through
the firewall, even when the device is on ActiveSync (unless I am
misunderstanding what ActiveSync does)
- I can always hit the web service on port 8080 using IE

I am actually getting a System.Net.Webexception, but because I cannot use
the debugger (it works fine when the device is plugged in), this is a pain
to pin down.

Interesting - I am indeed coming in through the local network when connected
to ActiveSync. I clearly see this in the IIS log:

2008-01-05 03:30:19 W3SVC259463726 10.10.1.110 POST
/CurrentTemperatures.asmx - 80 - 10.10.1.176
Mozilla/4.0+(compatible;+MSIE+6.0;+MS+.NET+CF+Web+Services+Client+Protocol+2.0.7045.0)
200 0 0

10.10.1.176 is the development box that the device is connected to.

But my WS URL is http://Dyndnsname.net:8080/CurrentTemperatures.asmx

So it seems that the some component along the way is stripping out that port
information, and that I am probably not getting in through the firewall when
disconnected.

I got it working, and it was indeed related to the port number disappearing
from the URL. In my web.config, the URL string has the port. When I
inspected the URL property of the soap client before the request, the port
was gone. I now set the URL explicitely in the code and it works as
expected: the application hits the web service when I am not connected (on
port 8080 through the firewall). When I am connected via USB cable, the
request fails, also as expected.

One more posting about this - the reason for this is was a really stupid
oversight on my part.
The URL (not in the web.config, of course, as I said previously, but in the
Web Reference properties) is not being used at runtime. Visual Studio only
uses it to generate various code that it does not show you. Because my web
service is not accessible with the external port from my internal network, I
was unable to "Update the Web Reference" with the correct URL. I ignored
this fact, and the generated code behind the scenes actually did not know
about the external port. There is no good solution to this other than
manually fixing the WS URL in Reference.cs and Reference.map.
