is a fully HTML-based application. It is secured with SSL and
certificates and securely transmitted via the HTTPS protocol. As such,
it is an excellent candidate for remote access.
The ECP can be accessed
by an administrator or specialist from any client using a supported
browser via the https://<servername>/ecp URL. End users can access
the ECP from within the Outlook Web App (OWA) client by clicking on the
Options link, which redirects the end user to the
https://<servername>/ecp, as shown in Figure 1.

The ECP also
functions across a firewall, similar to Outlook Web App. It is
recommended to proxy the HTTPS traffic through an application level
proxy firewall such as Microsoft ISA 2006. Figure 2 shows an example of ECP access using an ISA proxy firewall.

The diagram in Figure 2 shows clearly that the ECP traffic goes to the Exchange Server 2010 CAS role.
