I missed the prior ones, but had I seen them, I would have told you to post
again, this time providing the usual diagnostics ... actually two sets of
them -- one from when the router is routing, the other from when it is not.
If you don't know what "the usual diagnostics" are, consult the SR FAQ
listed at the end of the message. Also, can the LEAF router itself ping out
to the Internet when in "failing" state?
Oh, one wild guess, based on your description -- I don't really know how
Kazaa-lite operates, but if it initiates a LOT of NAT'd connections ...
might you simply be running out of ports to NAT to? (I've seen occasional
reports of this happening, but it takes a lot of activity plus long NAT
timeout settings. And I can't think of why the "fix" you describe would
work for this, anyway ... that's why it is a wild guess.)
