If performance and technical requirements are known and one is familiar with Cisco® ASA Security Appliances, the comparison tables are useful to select a comparable firewall for a particular application. Hacom offers several firewall systems utilizing the pfSense® software.
Using iperf, the IPSec site-to-site throughputs of the Cisco ASA 5510 were measured at 66 Mbps for both 3DES and AES-256 encryption. In comparison, the Mercury pfSense appliance's performance was measured at 77 Mbps, and the Mars pfSense appliance's performance at 100 Mbps.
You will need to add a firewall rule to the WAN interface allowing access from an external source. By design, pfSense is supposed to work correctly with minimal configuration. The WAN interface is protected by firewall rules that are not visible from the WebGUI. Allowing external access is a security risk, which requires the admin to understand before proceeding with the decision.
The error message: "acpi_tz0: _TMP value is absurd ignored (-269.7C)", shows up and clutters the console starting from pfSense version 1.2.1. It is harmless. Current releases of FreeBSD chooses not to ignore some of the ACPI mis-implementation and reports them as such.
