I don't know if you need qualify, if you're already doing register.  But 
you should probably set your registration interval to be pretty low, 
because linksys routers time out NAT tables very quickly.

I know that they time out valid, but idle TCP connections after about 15 
minutes or so. 

(I'd set the registration interval to just a few minutes).
