Exchange 2003, outlook 98.
Local clients connect with no issue,

I have had internet clients connecting via exchange connector thru the
firewall at thie location before with no issue, until code red came out...
and due to an unqualifed admin and/or a patch issued by microsoft, this has
stopped working.

Ports open on the firewall: 25,80,110,135,143,593 and opened range 1024 to
1800 based on something I read.
The exchange client "sometimes" connects to check the username with 10
second pause, othertime it reports connection or network error.

I have statically set the tcpip ports for exchange as well based on some
articles posted by microsoft, saw no improvement and removed them.

I am 5 hours into this...what have missed to get this to work?
