OWA and Remote Web workplace over PIX firewall

Hi everyone,
I am having a tough time here.  I am trying to get Outlook Web Access (OWA) and Remote Web Workplace (RWW) to work over a PIX firewall.  The server is running Microsoft Small Business Server 2003.  I have OWA and RWW running on a SSL cert INSIDE of the firewall just fine.  However, once I try to access it through the PIX, I get nothing.  Check out my code below.

Important IP's :  My server 10.100.100.2
                         PIX inside interface 10.100.100.1
                         Our ISP static IP 24.x.x.30
                         Our ISP gateway IP 24.x.x.1

Not sure, but you need port forwarding of  port 25, 80, 443 , 3389 from the outside to the SBS server on the router. That's it.


I hope this helps !
ALso need to have a Public DNS IP on the router.

I have all of that.  The "ip address outside 24.x.x.30 255.255.255.0" statement is setting my ip address (and yes it is a static IP from the ISP).  Also, ports 25(SMTP), Port 80 (Http), Port 443 (HTTPS), and port 3389 are enabled as far as I can tell unless there is an error in my code.  Any pix experts out there with some insight?
Try this:

no static (inside,outside) tcp 24.x.x.30 smtp Server smtp netmask 255.255.255.255
no static (inside,outside) tcp 24.x.x.30 https Server https netmask 255.255.255.255

no access-list fromoutside permit tcp any host 24.x.x.30 eq 4125
no access-group inside_access_in in interface inside

These commands are essentially just changing the syntax of your existing static translations and access list statements to the syntax Cisco recommends when performing port redirection.  You also can remove the ACL applied to the inside interface since that is the default behavior anyway.
