Subject: Connection tracking UDP
Date: Tue, 30 Sep 2008 14:30:37 +0200	[thread overview]
Message-ID: <740c3aec0809300530y2b87c478rf0029fd26e6e8567@mail.gmail.com> (raw)

Hello all,

I have a problem with connection tracking, specifically that sessions
persists and are being erroneously reused.

For example, host A connects to host B using UDP via C and C adds one
session for the connection and puts it in the [UNREPLIED]
state. Shortly thereafter A reboots and will again try to connect to B
via C. Now the connection tracking seem to reuse the old session which
was in the [UNREPLIED] state. This causes strange problems with
dropped packets.

My question is, what is going on here and what can be done about it?
Is there even a point in connection tracking UDP connections when
problems like these occur?
