Hi
Sorry I have some changes in my question as I am confused initially.
linuxbox (p.q.r.t)
|
|
INTERNAL ------ ABCD ----- INTERNET
(p.q.r.s) (m.n.o.k)
ABCD has 3 interfaces connected to linuxbox, INTERNAL N/W, INTERNET.
I am able to ping from INTERNAL to linuxbox. So there is a path
available in routing table.
At present I am snatting the packets from linuxbox 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 in
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.
