I use a DX-33 for my firewall/NAT box, and it never even breaks into a sweat.
Considering that the difference between a 486SX and DX is only that the SX
has no hardware floating point (as opposed to the 386DX/SX which had 32-bit
and 16-bit data busses respectively) I'd be happy to use it as a firewall.

You could also put a multi-port serial card in there, bung ssh on, and you
then have a nice ssh-able terminal server.  Terminal servers are good.
ssh-capable terminal servers are even better.
