All, I have been using my Buffalo router (WHR-HP-G54 Wireless-G MIMO) (with latest Tomato firmware) as a hardware firewall for some time. Is there any practical benefit for me as a home user to picking up a ZyXEL ZyWALL 2 Plus to use as a firewall instead of the Buffalo? Right now, I "VPN" into my home using OpenSSH. I note the ZyWall is IPSEC-based. Thank you.
