MS Exchange and pfSense

[mingoad]

Hello,

We need help with our pfSense configuration so that our Outlook clients can connect to our MS Exchange 2003.

In our LAN our Outlook clients work normally, but outside our network they can't connect.

We have open in pfSense all the ports that appear in this website:

But still our Outlook clients can't connect, even though they have no problems connecting through OWA.

If you have any suggestions on how we can fix this, please let us know. We need to fix this ASAP    :-\

Thanks,

Mingo

When you say "open" - do you mean you forwarded them?

Have you tried the use of HTTP - as detailed here in this linked article?
