If you linksys will do that, yes it is perfect ... mine has very limited
port forwarding capability ... it only forwards a port (say 22) to the
same port on one machine.

No way to set more than 1 external IP or port forward 3333 -> 22 ...
3333 -> 3333 only  and  22 -> 22 only.  That is how mine works :(
