Unhappy Packet Filtering



Hi everyone,

Here goes....

I am using Redhat 9.1 as a host for a virtual lan ( the host is connected to two XP machines (virtual) built in Vmware).

I am capturing packets sent from socket programs (port 2000) on the virtual XP machines through the lan and sending it to a simulator running on the Linux Machine.

Problem: I need to block the original packets and allow only the duplicates.

I tried to use ip_tables but couldn't really understand it ...(truth is i am afraid to mess up)

any suggestions....

Setup :
Virtual XP (vmware)<====Linux host =====> Virtual XP (vmware)
| |
\ /
NS2 simulator

the simulator NS2 is on linux host

PLEASE any suggestions will be helpful... my thesis depends on it...
Thanks in advance.
