Hello,

I'm using COBALT Cache RaQ 2 with 256MB RAM running NetBSD/cobalt 4.99.4
as a NAT router in my room. The outline of my use is like this:

   -----------+----------- main stream (connected to the Internet)
              |tlp0        OCN registered /29 network
            +-+-+  \
            |RaQ|  NAT
            +-+-+  /
              |tlp1
     ---+-----+----------- private subnet (testing network, 192.168.1.0/24)
      +-+-+
      |P C|
      +-+-+

Here, when I download large files such as iso images of NetBSD or Solaris
Express on PC, the traffice rate at tlp0 and tlp1 decreases and finnally
it becomes zero. And the PC gets offline.

My assumption is following. What is the possibility?

1. RaQ 2 is too slow to handle large traffic.
2. The HUB I'm using on private subnet is too weak.
3. tlp(4) has some problem.
4. other

If 3 is the true reason, what shoud I do to debug or improve it? Do I have
to show more information about my RaQ2?
