Hi Below is my network setup. linuxbox | | INTERNAL ------ ABCD ----- INTERNET (p.q.r.s) (m.n.o.k) ABCD has 3 N/W interfaces connected to linuxbox, INTERNAL N/W, INTERNET. Linuxbox has a private-address and it is not in the same subnet as INTERNAL N/W. I have to do snat packets from linuxbox to INTERNAL N/W or to INTERNET at ABCD. I have a small doubt regarding the FTP from linuxbox since I have to support ftp from linuxbox to both INTERNAL N/W as well as INTERNET. How can I right a rule in iptables present in ABCD where it can decide if the destination ip-address of ftp server is within INTERNAL N/W or in INTERNET and do natting accordingly. -- Thanks, Ajith --------------------------------------------- www.codingfreak.blogspot.com -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
