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? --=20 mvh Bj=F6rn
