I need a MAGIC BOX to do this

(eg convert something like 192.168.5.191/3660 to something like
192.168.5.100/222
but this is just an example).
Can anyone suggest anything? Preferably with a router (we have Linksys
BEFSX41)
or with CentOS 4.5 (would have to be on the outgoing side).
You can do this with a trivial iptables setup, although you will want to
use some thought about the setup, use DNAT on the incoming packets. I
would worry about overhead, but if you have enough capacity to run 100
copies of MySQL, you have either tons of capacity or larger problems
than iptables overhead.
What it actually will be used for is to run 100 or so instances of mysql
on the same
machine but on different ports. Then each instance of mysql will have
its onw logical
IP address.
