Sorry for late reply: A few vacation days. By the way, I don't clearly understand the question. At first glance it is not related to ICS component but to ISA configuration.
> couldn't connect to TWSocketServer. First check the connection from the ISA server (I mean the computer running the ISA server), for example using windows command line telnet. If it doesn't work, check for connectivity between the computer running the ISa server and the computer running your TWSocketserver based application (firs try to ping it). If connection work, then your problem is related to ISA server configuration and sorry, I can't help (and anyway it is out of topic here). -- [EMAIL PROTECTED] http://www.overbyte.be ----- Original Message ----- From: "Paul Barratt" <[EMAIL PROTECTED]> To: <twsocket@elists.org> Sent: Monday, April 03, 2006 6:07 PM Subject: [twsocket] TWsocketServer behind Microsoft ISA 2004 firewall > couldn't connect to TWSocketServer. > > TWSocketServer app on win2k machine on internal network. > (built with delphi 2005 and ICS ) > Microsoft ISA 2004 server publishing rule to publish TWSocketServer app on > port 3000 > (TWSocketServer.Addr set to internal ip address of win2k prof machine) > > ISA has a publishing rule property that says either > a). requests appear to come from ISA server machine > b). requests appear to come from original client > > When ISA is set to (b), the default, I cannot connect from the Internet? > but when it set to (a) and the connection appears to come from the ISA > server machine > (another internal IP) it connects ok? > > Is this because the connecting IP is not in the same subnet if its from > the original client (external) ? > > I'd like to understand whats going on here as it took ages to stumble upon > the solution. > > Thanks, > Paul. > > > -- > To unsubscribe or change your settings for TWSocket mailing list > please goto http://www.elists.org/mailman/listinfo/twsocket > Visit our website at http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
