I think the new mac ageing (sometime since 2.6.8.1) may be too aggressive. Now it updates the table at a much later time, with a comment in the code that leads me to believe this is to prevent counting spoofed packets and a DOS. My problem is that the update occurs after the netfilter hooks which may do weird things to change the course of the packet so that it does not get counted. (in my case, redirecting, queueing to userspace, nonlocally bound sockets, etc). For me this causes packets to go spewing out on the wrong interface when the timer expires. I used the attached patch to revert back to the old method. -Dirk -------------- next part -------------- A non-text attachment was scrubbed...
