hi! can somebody tell me more on this: when you develop a packet filter,
this is almost always to be run on a router/gateway. now, which interface
of the router is it attached to? and how is it done(in linux, specific)?

what i mean is, packets attached to which iterface(2 ideally of the
routers) are given to the packet filter? in a case, i have read of 2
filters placed, on either side of ann app. gateway, one filtering incoming
packets and the other one filtering outgoing packets. is this possible for
one filter employed at a router(with 2 interfaces), the question is can
the packet filter access packets coming from both interfaces and how does
he make the decision of forwarding/not forwarding? sorry if this is
another faq. thanks in advance.
