Packet Filtering
 

:confused: :cry: :cry: :cry: :newbie:
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.

there are many packet manipulation tool available using iptables. i guess i am not clear about what exactly you are trying to acomplish, sorry. if you could help me understand i am sure we could come up with a rule.
