[Bug 77] a bug in the chain PREROUTING of the table nat
...rmal. The 'nat' table is traversed for every _first_ packet of a connection. You can delete all nat rules, but already-established connections will remain active (and NATed). Due to the connectionless operation of UDP, we cannot tell UDP sessions apart if they use the same (scrip,srcport,dstip,dstport) tuple. Apart from that, your -t nat -I PREROUTING -j DROP rule will also only consider the first packet of every connection. It seems like you have some misunderstanding about the semantics. ------- You are receiving this mail because: ------- You are on the CC list for the bug, or...

Frequent RRL false negatives when using multiple server processes on Linux
...the same CPU, and configure process scheduling to tie a single NSD server process to each of those CPUs. (Too complex for us! And of course this has it's drawbacks, too, wrt load distribution at least. And unfortunately our Intel igb NICs only can choose the receive queue based on IPv4 srcip,dstip tuples but all IPv6 packets end up always in the same queue.) FWIW, the unblocking seems to be triggered every time by this, around line 425 of rrl.c from nsd-3.2.16: ----- } else if(now - b->stamp > 0) { /* older bucket */ int olderblock = used_to_blo...
