Hi there, Recently I was using a Linux box with IP-masquerading to share an IP address between some Wintel machines. Net access is provided via an Ascend Pipeline (combined router/ISDN modem). I have MS-Outlook 98 as my mail client on one of these machines and I am using an MSExchange server. Unfortunately, the Outlook client does not work in such a configuration - it hangs when attempting to connect to the exchange server. I believe that the tcp ports that are used for communication between Outlook and Exchange are negotiated dynamically and so I cannot use a port redirect (?). I do not have a choice as to which mail client/server that I use. It is awkward to have to peridically change the network config of my wintel machine and connect it directly to my pipeline just to synchronise mail boxes. Using the netstat command on the wintel box reveals that 4 different tcp connections are established between Outlook and the Exchange server, e.g.: C:\WINDOWS>netstat Active Connections Proto Local Address Foreign Address State TCP mypc:1129 FileServer.a.b.com:nbsession ESTABLISHED TCP mypc:1134 MsExchangeServer.a.b.com:1040 ESTABLISHED TCP mypc:1138 MsExchangeServer.a.b.com:1057 ESTABLISHED TCP mypc:1142 MsExchangeServer.a.b.com:1040 ESTABLISHED TCP mypc:1146 MsExchangeServer.a.b.com:1057 ESTABLISHED The destination ports on mypc are different each time Outlook is invoked. I would really like to find a solution to this as I am just about set up exactly the same situation in my home and this is a bit of a show-stopper. Has anybody come across this before and if so do you have a solution or any suggestions? If it required some coding and somebody could point me in the right direction I would consider having a go at implementing a fix myself.
