Let me try to explain this:
BoxA talks to 2 boxes, FE1 and FE2.
Somewhere along the way something happens and BoxA sends a reset (RST) to FE2.
Now, while looking at the network log the RST packet contained an ACK number
that was obviously meant for FE1. I know it doesn't matter what the ACK number
in a RST packet, because the connection is going to be terminated, BUT this
brings up a few questions:
1) Why did BoxA send the wrong ACK # to FE2? Does the OS share "TCP buffers"
with both connections?
2) Doesn't this present a small security problem since FE2 now knows information
about the current FE1 connection?
Someone smack me with enlightenment please.
