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.
