Please > suggest me the method of doing this Presuming the datagrams originate on one card and are destined for an address/subnet on the other card, enable IP forwarding (`echo 1 >/proc/sys/net/ipv4/ip_forward`) then add rules to your FORWARD chain that define which packets may and may not pass. If you can be more specific about what sort of information you want to process for, how your network is setup and what exactly you are trying to achieve we will be able to help more. David
