Viewing TCP / UDP Ports for Spam Firewall Config

We just received a Barracuda Spam Firewall 200 for the company I work for.
We are trying to integrate this into our current Cisco ASA 5510 Series router.
The directions for the spam firewall say we should open the following ports:
PORT       DIRECTION       TCP       UDP       USAGE
25            In/Out               Yes       No         Email and email bounces
53            Out                   Yes      Yes       Domain Name Service (DNS)
80            Out                   Yes      No          Virus, firmware and spam rule updates
123          Out                    No       Yes        Network Time Protocol (NTP)

There is a web interface I can access by typing in the IP address of the router and logging in but I can't make any changes through this interface even if I wanted to because the password to access this interface isn't a high enough level.
If I use Hyper Terminal I can use the EXEC password to log in and this will allow me make actual changes but I am not familiar with the Hyper Terminal interface.  I don't even know what I am looking for or what to type in.

Any help would be much appreciated.

This is a somewhat involved configuration, you may want to think twice about doing it yourself if you have no experience with this kind of thing. You have the potential to break your email connectivity. That said...

If I understand correctly, your new Barracuda is going to be a host (in your DMZ I assume?), and you wish to open the firewall to allow these ports into the barracuda's NAT address which you will also have to create?

I will also assume you have existing internal email server(s) that handle your in and outbound mail now?

As part of the process, you will also have to repoint your DNS MX records in public DNS to the Barracuda NAT, and set up your email server to send/recieve mail through your Barracuda.
