Problem iptables Forwading
I have a rule that redirects the port 8080 from any external IP address to an internal server. I have no problem with the majority of clients. The forwading works great but I have a problem with only one IP. I logged the traffic and the prerouting works and the forwading works but it get stuck with the SYN tcp flag so the conection is never established.
Logging the traffic form any other IP there is no problem. I can see the Syn flag and then the Ack flag ..
I'm sure I'm missing something, but I can not find out a solution
Thanks in advance.
