<div dir="ltr"> Dear All, I am having a problem with configuring IPTABLES My Setup : Fedora 6, as a proxy server having three NICs as follows eth 0 - not in use eth1 - IP (<a href="http://192.16.251.234/" target="_blank">192.16.251.234</a> gw - <a href="http://192.16.250.246/" target="_blank">192.16.250.246</a>) Connected to LAN eth2 - IP (<a href="http://192.16.250.246/" target="_blank">192.16.250.246</a> gw - <a href="http://192.16.250.245/" target="_blank">192.16.250.245</a>) Connected to router of ISP LAN has the mix users of Ubuntu and Windows We are using squid (with NTSA authentication) for HTTP traffic, which is working fine. My Problem : I want my users to use ftp to upload file for different reasons. Thus any FTP traffic (only ftp) at eth1 should be route to eth2, such that to connect to ftp site and upload the content. I have tried ip_conntrack_ftp but does not helped. Can any body help me to route the ftp traffic regards Arun </div>
