The Barracuda WAF (Web Application Firewall) model 660

Initial Setup:
Unlike "higher quality" systems, the barracuda systems needs a keyboard and VGA monitor for the initial configuration. When plugged in, login with the default user/password (admin/admin) and in the System Configuration window, navigate to the TCP/IP Configuration. From there, enter in the following information:
- WAN (external) IP:
- WAN Mask
- WAN Gateway
- Primary and secondary DNS servers. (Note that the Barracuda's Achilles heal is the external DNS system. It requires this to work properly, so make sure that it is robust and accessible by the Barracuda.
When you are done, select save and exit. The changes will be made instantly.

Setup Outbound Firewall Rules
The system must connect to the Barracuda Network to handle licensing. (this way they can milk the hell out of you for an over priced support contract. :) Without this, the system throws errors and behaves poorly for admin purposes. To enable this bend-overage, allow the following outbound flows on your firewall:
Allow TCP:80 from the Barracuda to the following networks
64.235.147.0 255.255.255.0
host 64.235.144.132
216.129.105.0 255.255.255.0
216.129.125.0 255.255.255.0
205.158.110.0 255.255.255.0

From the Basic tab, under Status, select (3) the "Click here for activation code". This will pull up a Barracuda webpage where you can enter in your company's information for the support contract. When you are finished, you will get an activation code, which you should paste back in (4) the Basic tabs Status page, under the Subscription Status.
