Hello,
In fact, this is not a bug. This is a problem on a 'chip' router. Also, your
router have a little nat table, and on the major 'chip' router (like zyxel
prestige 310 ...) the nat table have only 255 entry. So, when you make a
connection to outside, you user more and more connection on nat table, and
after a moment, the router haven't finish to refresh the nat table (after dead
connection, timeout connection ....) that you ask a other and you flood the nat
table. A this time, when you as a new connection, the router drop the packet
because his internat nat table is full. The connection appear down, but not it
is.
The arround is to config mldonkey to open max 100 connection , and if possible
disable overnet (nat is for incoming and outcoming packet).
Or by a other router. I have change my prestige 310 by a cisco 1605 (with
ethernet modem) and i limit the nat table to 3072 entry to the nat table. Then,
i can use 600 connection in same time (the cpu of cisco router is 40% of use).

In my opinion this is also a bug with the firmware on the routers in question,
no amount of bad traffic should _ever_ hang the router.

same problem for me here. lowering the mtu of the ppp-device
apparently helped in preventing the problem to appear for a few hours, but it
still appears :(
