I have a problem with iptables. This is the configuration +---------+ +---------+ +---------+ | | | | | | | A +-----------------+ B ++----------------+ C | | | | | | | +---------+ +---------+ +---------+ A sends UDP packets (ports p1, p2, p3) to C through B. There is a continuous flow of UDP/p1 packets (10 packets/s) whilst p2 and p3 are more seldom. When I activate a rule to redirect all UDP packets from A to B the rule seems to be applied only to p2 and p3 ports, p1 packets are still forwarded directly. Is there a form of caching mechanism that explains the fact that the packets are treated differently ? Thanks for your help Regards, Pierre JUHEN
