BlankI think one of the very best options is pfSense. Free Open-source, but it's BSD based, rather than LINUX based. As such it has a lower risk of external exploits. The user-interface makes it incredibly simple to set up and maintain. There is an embedded versions of it available to run on affordable/reliable solid-state, diskless, fanless Soekris/PCEngines embedded system boards.
It's incredibly powerful, and It's ROCK SOLID. I find the traffic shaping engine to work without a hitch. PFSense can do anything you want including VPN (PPTP, IPSec, OpenVPN), failover (Multi-WAN), IDS/IPS (snort) The NEWEST embedded version 1.2.3 rc3 (1.2.3-release is very close) can run the sipproxd package as well as many other packages that previously required the FULL version.

Hi, My customer has a outdated firewall that is also presenting a NAT nightmare for getting the Asterisk server reachable from the internet. What firewalls work good with VOIP? I really want to steer away from any ALG supported firewall. I just want a good firewall that works well with Asterisk. Thanks, David Wathen
