Right i have a problem which doesnt match any of the know methods of DoS
that i am familiar with. Basically the inbound traffic starts to climb but
the out bound traffic stops totally. This goes on for extended periods of
time and them stops totally. I was looking at ICMP echo_requests but this
doesnt really match the pattern of what i am seeing.
I was wondering if anyone know of a security breach/DoS problem which would
cause this.
the inbound rises to 20+meg per sec and the out bound stops totally, in
bound pings take over 400ms (normally 12), and we have 60-80% packet lose.
Rebooting the firewall doesnt solve this. But the problem went away some
time later. any suggestions are welcomed.

(1) What Kind of connection are you using? Shared T3/DS3/T1/etc?
(2) What firewall are you using? What OS is it running off of? Or is it a
hardware-based router (an appliance). What do your IPTables look like (if
Linux)
(3) Can you provide some logs that we could look at to better see what is
going on?
