Can't access OWA or Remote from outside of the company.

I have inherited a new server. SBS2003. It’s configured and working fine, however, I can’t figure out how to get to the owa! I put in and nothing comes back. The owa is working because it can connect to it internally. The problem I have is I can’t confirm that is the correct address set in Exchange.
What am I missing? I have setup exchange server times with no issues so this is really stumping me. I am not sure what the prior tech did. How do I confirm that going to is the correct address?

do you have mail record on the external DNS zone ? is it points to your exchange public ip address ?

do you have a port forwarding ( 80 or 443) in your external firewall, if any ?

then please telnet on port 80/443 from external machine

telnet external_ip_address 80

also, can you access owa by ip address ? if not then it seems to be a firewall forwarding issue. do you use ISA to publish owa, or another firewall ?

I did a test and it says port 80 and 443 are closed. All the others are open and I configured it the same way! Okay..gotta call the firewall manufacturer.
