What is "my pc" (the one with two lan cards) running? If it is running
FreeBSD, or you are considering using FreeBSD, look at this part of the
handbook:

<http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network-routing.html>

It is not clear to me if you want pcs on the two LAN segments to ping each
other, or be prevented from reacing each other. If it is prevention you
want, try here:
