Re: [FW-1] Exchange doesn't send e-mail notification through fire wall
Title: RE: [FW-1] Exchange doesn't send e-mail notification through firewall
You have to configure Exchange to use predefined ports. You have to set this up manualy through the registry. Check Microsoft support article Q148732 for the details.

Subject: [FW-1] Exchange doesn't send e-mail notification through
firewall
Howdy,
I moved a number of PC's to a protected network (FW-1 NG.FP1). The PC's
on the protected network are allowed to access anything outside their network
but nothing is allowed in. Unfortunately the users need to have
access to the local virus factory, euh I mean Exchange server. This is still
possible since they are allowed to access anything outside their network,
however it turns out the Exchange server sends a UDP packet whenever the
user gets a new mail. So now the users don't get an automatic warning
anymore but instead they need to press 'check mail' every once in a while.
Unfortunately the Exchange server does not seem to use a fixed port
for sending those packets so I can't just allow that specific traffic.
Is there any way to get around this so the users get their notifications
again?
Nico
