Hi !

- I have a winform application connecting to a remote object hosted in iis
6. I used a 'soap' formatter.
- My IIS is reacheable from the internet on an address like
http://www.myserver.com/myserver/myobject.soap
- There is no proxy.
- There is no firewall and the IIS box is part of a lan with port 80
forwared to it's address.
- The windows firewall is turned off on my machine for testing.
- This application uses dotnet 1.1.

When I use my winform application from a machine on the LAN (192.169.1.4)
connecting to my remote server
http://www.myserver.com/myserver/myobject.soap it works fine. (and when I
ping www.myserver.com from this machine on the LAN it returns the public IP
address).

When I use the same application from the same machine out of the LAN, from
the internet, I got: "The underlying connection was closed: Unable to
connect to the remote server". This message comes after 20-30 seconds. I
tried tcptrace to check what was going on, but it wasn't helpful.

- I checked IIS logs, didn't found anything.
- IIS has "keep Alive" checked

I don't know where I could search to solve this problem...

Thank you,

can you try the following from the same machine out of the LAN?
http://www.myserver.com/myserver/myobject.soap?wsdl
and see the output.
I feel that it is a general network error .
are you able to access any aspx page from the same server outside of the LAN?

Yes, I got the wsdl without problem.... I can access any aspx pages from the
same server outside of the LAN (there is a public Website on this server).
