Overview:
The Barracuda WAF (web application firewall) 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
