Ok, step one:  Put a router/firewall behind that tellabs.  It should be
the only thing on your premises with a public routable address.  Yes,
that will make your SIP configuration a touch more complicated, but
you've already seen the balancing cost...

Go pick up a copy of Firewalls and Internet Security from O'Reilly,
find a quiet corner and a pot of really *hot* tea, and sit and read it,
assuming you can't pay someone else to do this for you.

But don't put *nix application servers directly on the net unless you
really know what you're doing.

And yeah, you're gonna have to wipe that box, as Steve said.
