Hi Philippe,
 
That is the PPTP control channel. Why would client use that for the
source port to connect to a Web server?
 
Thanks!
Tom

        Hi all,
         
        In our lab, we're testing ISA server. We try to use web
publishing, it seems to work except when a client (supposed to come from
the Internet) connects to ISA with port 1723 (client side) on port 80
(server side). 
        In this case, the TCP packet coming from the client is as:
            client:1723 to server:80
        But the answer of ISA is
            server:1025 to client:1723
         
        This answering packet is then blocked by the built-in firewall.
         
        Any idea ?
         
        Any feedback about the Feature Pack ?
         

        Cordialement / Regards
        Philippe WEHOWSKI
