Configuring NAT/Basic Firewall, on the "Address Pool" tab > Reservations...
Reserve Addresses > Add Reservation or Edit Reservation sheet, I see a
Click to expand...
checkbox labeled "Allow incoming sessions to this address."

Whether checked or not, external users can browse my internal web server.

Can someone explain, in lay English, what the purpose of the checkbox is?
What should I notice in the system if it's checked or un-checked?

Thank you.
 
which interface type are you using? Private or public?

By default, on the "NAT/Basic Firewall" tab:
- "Public interface connected to the Internet" selected.
- "Enable NAT on this interface" checked.
- "Enable a basic firewall on this interface" checked.
 
that doesn't make sense. but try this.post the result of netstat -a.
