Re: help iptables queuing

["Paridhi Bansal" <paridhibansal@mail.com>]

hi

how do i check that whether conn tracking module is installed or not??

Actually, this problem was not coming earlier..suddenly has it statred coming..now what is really puzzling me is that when i also queue packets from FORWARD chain(i did this just to check in case pkts were being directly sent to this chain instead of prerouting), i receive all the packets through prerouting, forward and postrouting chains..and when i change the FORWARD back to ACCEPT all without queuing, again,the same problem..i receive only the first pktof every TCP session in prerouting and postrouting chains....

Hi

Is your kernel compiled with connection tracking support (either in the
kernel, or as a module)?
