This is admittedly off topic, but it also seems like a good place to ask
the question. We currently have a bunch of Juniper firewalls to handle
our VPN tunnels. We are pretty happy with them, but they tend to max out
at around 100-200 tunnels each because of limitations in CPU
performance. I would like to find a good Linux alternative because I'm
thinking that we should be able to cram 500 tunnels onto a multi-core
Xeon server pretty comfortably. Does anyone know a good Linux-based
firewall/VPN solution? I've Googled, but mostly I just see references to
OpenSWAN and SmoothWall. That would probably be fine if I could find
some case studies where people used those tools in high-load
