Consume webservice within intranet from internet

Hello.

I have a webservice located on a machine within our network. I have
developed and tested this webservice internally without having to worry
about credentials. Now I wish for web applications located on a server
outside the network to be able to consume this webservice. I do not
want to put the webservice outside the network, and only want to allow
a handful of web applications to be able to consume it.

The error I'm getting is as follows:
--------------------------------------------------------------------------------

The underlying connection was closed: Unable to connect to the remote
server.

Upon some researching I found articles about HTTP Proxy server/firewall
settings messing with the connections, resulting in the previous error.
So I made changes to the web.config and the way that I call the
webservice.

Web.config:

<system.net>
<defaultProxy>
     <proxy
          usesystemdefault = "false"
          proxyaddress="http://proxyserver:port"
          bypassonlocal="true"
     />
</defaultProxy>
</system.net>

I call the webservice as follows:
        Dim ws As New myServices.webservice
        Dim myProxy As New WebProxy("http://proxyip:proxyport", True)
        ws.Proxy = myProxy
        ws.Credentials = New System.Net.NetworkCredential("name",
"password")
        Dim asdf As String = ws.Process()

I still receive the same error and am running out of ideas. Please
help.

Thanks.

i use this :

copy paste from one of my projects

Dim MijnistaWs As New wsMijnista.mijnistaWebService
            If My.Settings.UseProxy Then
                Dim pr As New System.Net.WebProxy(My.Settings.ProxyAdres,
CInt(My.Settings.ProxyPoort))
                If My.Settings.DefaultCR Then
                    pr.Credentials =
System.Net.CredentialCache.DefaultCredentials
                Else
                    Dim cr As New
System.Net.NetworkCredential(My.Settings.proxyUname, My.Settings.proxyPass,
My.Settings.ProxyDomein)
                    pr.Credentials = cr
                End If
                MijnistaWs.Proxy = pr
            End If

This works for me in all situations , ofcourse i have a settings screen
where you can choose for a direct connection , or connection through a proxy
with the default login values or by alternate values .
