Hi !! We are seeing a lot of packets being blocked at our firewall, coming from our webserver, port 80, going to the several hosts at the Internet, at high ports, with both SET and ACK set. It seems that these packets are answers from our webserver to connections estabilished to it, and, for some reason, their state is not being kept. How can I track this problem? We are using iptables 1.3.1, kernel 2.6.11.12, in a Fedora Core 3 machine. Thanks in advance, Carlos.
