Are you sure that port isn't blocked or a firewall is stopping you?  Those seem like the most likely culprit unless you changed the IP of your Exchange CAS and forgot to update external DNS or something.

Thanks

The ip of the servers are the same. And the new router has the same ip with the old one. Also i disable now the firewall of the router. I dont know actually if i have some errors with the ports i opened in the router. What ports i have to open and in which server each?

You may need to open the following ports, depending on the services you want to make available:

Port 25 TCP – SMTP (Outgoing Exchange e-mail)
Port 80 TCP – HTTP
Port 443 TCP – HTTPS (RWW, OWA, remote desktop or Terminal Server sessions)
Port 987 TCP – External secure Companyweb access
Port 1723 TCP – PPTP (VPN)

Unless you changed something OWA should be using port 80 for HTTP and 443 for HTTPS (SSL)  What exactly happens when you browse externally to the site?  You really shouldn't even have to enter the port.  You should just be able to go to mail.domain.com assuming you have external access configured correctly and have the login prompt or some OWA error.  Do it even resolve at all when you do that?

You simply need to enter the IP address of your Exchange CAS and the Port you want opened.  There is no reason you would need to make your Domain Controller external at all.
