Hi,
Astaro is a commercial product that is free for home use, therefore it includes 98% if the m0n0wall and pfSense features plus a whole lot more.
Besides a complete packetfilter/NAT gateway, you have a full WebSecurity gateway including free commercial AV engine and a full MailSecurity Gateway including a commercial grage AV and Anti-Spam engine.
If you have not used it before, check out
http://demo.astaro.com to see if the userinterface is easy to use.
The home-use edition also includes full firmware and pattern updates for free.
On top of that, astaro offers a complete free central management solution if you need to manage multiple Astaro Gateways.
I hope that helps,
regards
Gert
