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.
