As I mentioned, SonicWall (VxWorks-based) and WatchGuard (Linux-based) are the "big 2" SMB firewall/VPN vendors for products costing $200-$5,000. SonicWall has per-user charges for many of their features, typically at the 25 and 100 user price-points. You'll find most appliances have this as well -- especially for added features. > You can try IPCOP or SmoothWall, free downloads, these are > pretty good also. Last time I checked, IPCop prefers private IPs. I could be wrong though. And it can be solved with 1:1 NAT and or SNAT/DNAT public IP pooling options (which might actually be better than using "raw" public IPs). -- Bryan J.
