Cisco ASA 5505 8.4 and configure for SBS 2011 Outlook Web Access

Hello,

We have successfully setup a new ASA 5505, 8.4 and got internet, SBS 2011 Exchange e-mail, as well as VPN running; however are having issues with external users being able to use Outlook Web Access successfully (works internally).

Currently the Outlook Web Access and another https web based application is stored on our SBS server, and users on the outside were previously able to access them just by going to; https://www.<outside IP address>/owa.  As of now, no one is able to reach this from the outside anymore and I suspect that the ASA is not allowing https access correctly. Can anyone assist with the ASDM config, so that users can reach the web app/Outlook Web access on our internal SBS server from outside of the network?  Thanks

Just from first glance this line looks incorrect

access-list outside_access_in extended permit tcp any 192.168.2.0 255.255.255.0 eq https

Should be

access-list outside_access_in extended permit tcp any object SBS_2011 eq https

thanks for the response smckeown777, I actually tried changing it to: "access-list outside_access_in extended permit tcp any object SBS_2011 eq https"; however users on the outside were still unable to access OWA.

Do I need to reboot the ASA, before theses settings kick in?  I tried making that same change previously, then just clicked apply and save, but did not reboot the ASA afterwords...and no go.

Sorry you are missing the NAT statement
You have this one -

nat (inside,outside) static interface service tcp smtp smtp

You need also

nat (inside,outside) static interface service tcp https https

I think that is what is missing, if not someone will correct me!
