My network is besieged by attempts to enter on port 6346; the person who put Limewire on the LAN has taken it off, but the router logs still show the attempts from outside. The LAN and my business is largely down.

Two questions:

How long till the machines on the outside figure out not to bother ? How is the code on the client side written to this issue ?

Is this actionable ? Can I sue Limewire for what amounts to a D.O.S. attack ?
