Hi Please advice, I am running a iptables 1.2.11 on Debian Woody with 2.4.24 kernel. I have a DMZ with 7 machines (4 linux, 3 windows) and 80 Windows machines on the LAN side. The windows machines makes a lot of tcp/ip connections with internal client machines (oracle and java). As certain time (around 4000 simultaneous TCP/IP connections) the machine running iptables drops connections and failures occur. Are there any kernel or iptables setting required to be set for such a large number of connections??? Please advice Thanks Mohan
