Firewall on Exchange server ? please verify with https://www.testexchangeconnectivity.com/
Run the Internet Conenction wizard on the SBS Console - this will also check the firewall is configured correctly.  Are you sure your external DNS is correct and pointing to your External IP for your Server?

External test are made from same LAN where server is? Try from other internet access, maybe firewall is blocking loopback.

Commented:
I assume you use different IP-s or DNS names for external and internal adresses.

If not, then you need to find out what is the external IP of your exchange address and whether it's a fixed or dynamic address.

I founds this which may help

"The issue is with the management port setup on the Draytek, the default management port for https is 443, you must change this to another port in order for 443 traffic to be forwarded to your server.

The management port setup is in the System Maintenance -> Management menu on the Draytek"

Port 80 is also in use by the Draytek, can be changed on the same page mentionend by crash2000.

I wouldn't open 80 to your server unless you really need too. Train users to use https:// not http://

Thank you very much for your help. I found that remote management was switched on and pointing to the same port.
