Hello:

I wanted to know if there is any change or stuff (like proxy web server) to use the calendar via Internet.

i.e.

i access the calendar on my networ througth http://hostname.domainname.com:portnumbre.

When i try to access via internet therougth www.domainname:portnumer, it cannot be accesible.

What are the procedures, by the way i have used the evaluation senario for this.

Thanks in advice.
