Every time my home router (running Attitude Adjustment) gets a new IP
address from its pppoe connection, all existing NAT'ed TCP connections
from my computers inevitably become instantly "obsolete".  Yet, those
computers aren't told about it, so those TCP connections don't
immediately die, instead they freeze and only get some kind of timeout
after a very long time (2h, maybe?).

Is there some way to make it so that when the WAN gets a new IP address,
all outstanding TCP connections that rely on the old IP address get an
RST packet?  After all, keeping those connections alive would only make
sense if there was some hope to re-obtain the previous IP address
"soonish", which is rather unlikely.
