I had a PPC machine running as a firewall/router for a while, a free linksys router is what I ended up replacing it with. I also used a 466 Celeron PC for the same task when I was experimenting with a linux firewall router.
To be honest a computer just takes up to much space and energy for a firewall, and as for an all purpose server I think a Win2k server based machine is best for multi platform use (works as a old mac server very well). I did and do use my WGS95 for a classic server (fast too) but I only fire that up as needed while my win2k server tends to be on 24/7.
Never did get around to running hotline on a LC3.. one of these days.
