Connection tracking UDP

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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?
