It was thus said that the Great Roy J. Tellason once stated:
   Indeed.
I am currently using (and sending this stuff through) a
 486dx2/66 for a firewall/router.  And when I get done with that one for
 whatever reason I have plenty more similar hardware to "use up" before I
 move on to the Pentium-class hardware,  of which I also have plenty. 
 They do have plenty of CPU power to act as NAT/firewall routers, but if
 you want to run ssh, you'll find them a bit on the slow side. 
 
 I SSH _to_ that box but that's about it.
  The 500Mhz PIII I replaced my P1 with now also
runs a squid proxy and an
 adblocker as well. 
 Squid was one thing that I know of that might prompt me to upgrade a bit
 sooner,  as it'd cache stuff.  I only have an adblock plugin in firefox but
 that seems to do the job just fine. 
 
  I have a 486DX2/66 that's my firewall/NAT system and it also runs Squid
(and I can SSH into it, but the initial login is a bit sluggish).  Runs
great.
  I also used a 486 as a webserver until a few years ago.  Had an uptime of
444 days when I shut it down for the last time.
