Hi,

Sunny's answer is good advice, let me just add a little more to it if
you want to use the object from inside and outside your firewall.
Check this article I wrote on the subject out.

Hi,

look inline your code:

//put there the external IP of your firewall
props["machineName"] = "xxx.xxx.xxx.xxx";

//this makes the channel to use the machine name we sppecified
props["useIpAddress"] = false;

[quoted text, click to view]
......
all other is the same


Hope that helps

Hi,
I'm a novice in remoting, and I've a problem trying to make it work over
internet.

I have a SAO (Singleton) named CampusDataAccessLoader. I want clients to
access this object in order to use it as a object-maker for another class
(CampusDataAccess). I don't need callback functions.
When I work in the LAN, it's all OK.
Well, the server code is the simply:

BinaryClientFormatterSinkProvider clientProvider = new
BinaryClientFormatterSinkProvider();
BinaryServerFormatterSinkProvider serverProvider = new
BinaryServerFormatterSinkProvider();
IDictionary props = new Hashtable();
props["port"] = 8989;
props["name"] = System.Guid.NewGuid().ToString();;
HttpChannel chan = new HttpChannel(props,clientProvider, serverProvider);
ChannelServices.RegisterChannel(chan);
RemotingConfiguration.RegisterWellKnownServiceType(
typeof(CampusDataAccessLoader), "CampusDataAccessLoader",
WellKnownObjectMode.Singleton);
While the client code is the simply:
BinaryClientFormatterSinkProvider clientProvider = new
BinaryClientFormatterSinkProvider();
BinaryServerFormatterSinkProvider serverProvider = new
BinaryServerFormatterSinkProvider();
IDictionary props = new Hashtable();
props["port"] = 8989;
props["name"] = System.Guid.NewGuid().ToString();
HttpChannel chan = new HttpChannel(props,clientProvider,serverProvider);
ChannelServices.RegisterChannel(chan);

Then the client gets the object with this instruction
DAL = (CampusDataAccessLoader)
Activator.GetObject(typeof(CampusDataAccessLoader),"Http://"+remserver+
":8989"+
"/CampusDataAccessLoader");
where remserver is the IP of the remote server

I'm using port 8989 because I've read it's firewall-friendly... but it seems
not !
I've a firewall on a server, and I've made a NAT on port 8989...
what I'm missing?
The error I'm getting is something like : System.Net.WebException:Underlying
connection closed. Impossible to connect to the remote server.
(The real message is in italian and is "Connessione sottostante chiusa:
Impossibile effettuare la connessione al server remoto").


But if i work on local network it works! So I suppose It's a firewall
problem...
Can some one help me?

Many thanks in advance!
