FP3 is nowhere near as Exchange/Outlook-aware as is R55 using the later HFAs. For instance, we had a lot of issues with the GAL coming up blank when trying to address a new email before the R55 HFAs fixed the problems.
Also, the "You have new mail" alert inside Outlook is sent from Exchange as a new connection using UDP. If the end user is not seeing the new mail envelope or pop-up or hearing the "bing", this is probably what is getting dropped. Ray
From: "Hui, Kiat (Contractor)" <[EMAIL PROTECTED]> Reply-To: Mailing list for discussion of Firewall-1 <[email protected]> To: [email protected] Subject: [FW-1] NG FP3 - Exchange & Outlook communications Date: Fri, 20 May 2005 14:49:44 -0400 Hey all, We are running Exchange 2000/Outlook 2000 in Corporate/Workgroup Mode. The Exchange servers are outside the NG FP3 and the Outlook clients are all inside. I have setup a rule to allow the internal network to access the Exchange servers using the "MSExchange" built-in Group under "Services". The logs promptly fill up with each client connecting to the Exchange server using 135/tcp and then some random tcp-port. Life is good. However, I then see a whole bunch of denied connections from the Exchange server to the Outlook clients on random udp ports. I am puzzled: Isn't the return communication supposed to be in the same state as the outbound traffic? Why are these connections being denied? Do I have to setup another rule that basically allows the Exchange servers to communicate on all high ports (>1024) to the Outlook clients? Without hard-coding the Exchange servers to talk back in a narrow range of ports (we don't have access to those servers), how have you guys been able to enable this Exchange-Outlook communication through the FW1?
