That's actually the one I have! lol! Today I use it to just see how much packet loss is happening across an ipsec tunnel so I am reminded of how sucky the isp is.
Back in the day we got it to reboot an old FVS114 router that we were using because it would reboot in 10 seconds flat--from power cycle to full traffic on it again.
We set the rebooter to reboot if a single ping was lost and the minimum gap between pings was 10 seconds, so the very maximum delay from the router locking up to it rebooting was 20 seconds. The rebooter worked so seamlessly that I actually forgot about the issue for a while.
The FVS114 was the 'core' in a hodge-podge network I built from things found in old storage chases since there was literally no budget for anything, but the current workflow for business wasn't working either. I was able to overhaul our entire infrastructure at 5 sites including desktops for well under $1000. As time went on, I was able to replace equipment with better stuff, but man was that FVS114 pushed well beyond its original specs of 'Up to 11.5 Mbps WAN-to-LAN, up to 2.1 Mbps for 3DES throughput'--it did 40Mb+ wan-to-lan and almost 20Mb on a tunnel. It was finally taken out of service after years of being pounded on. I think I still have it somewhere along with a dual wan version of it that didn't even do half of what this one could do.
