The reason why I thought of it was because it kept happening to me back when 
I was using a D-Link DSL-500 to provide my ADSL connection. Unfortunately...

... if they’re using a typical consumer ADSL router box like the above, they 
may not have any NAT table timeout settings to play with to cure the 
problem. I certainly couldn’t find any in mine.

In my case, I solved the problem by using a Linux box as my router.
