A dynamic IP address is assigned at boot using DHCP. There is no facility to assign a static IP address.
Syslog is not supported.
Alert (XML file of blocked requests) and activity (plain text file of HTTP traffic) log file sizes are limited to 1M each.
The listen IP address cannot be specified. It defaults to all available IP addresses.
The IP address on which to bind when connecting to the Web server cannot be specified. This is a practical limitation in very rare situations.
No support for standard W3C extended log file format.
While SSL termination is fully supported, the certificate and key files are not permanently stored and must be re-uploaded after a reboot.
The dynamically-generated Intended Use Guidelines (rules) are not permanently stored and are lost after power loss or reboot. Please note that the Intended Use Guidelines will be rebuilt automatically during run-time, but you may be required to enable Passive Mode for a period of time to avoid false-positives.
Some user-defined policies can be more difficult (or impossible) to define in the LiveCD version. Please see the user guide for details.
While wildcard characters such as '*', '#', and '?' are available, regular expressions are not supported for user-defined policies in the LiveCD version.
Because no HDD is mounted (16M RAM disk only), there is no swap, so when physical memory is exhausted, the system may fail.
Updates are available in the form of a new ISO image. Most of the configuration profile (properties) can be saved to a local storage device and re-uploaded after the update, but all reboot-related limitations listed above would apply.
