via fxp0
will match a packet either coming in or going out on fxp0.
in via fxp0
will match a packet on the way in and comes in on fxp0.
out via fxp0
will match a packet on the way out and if the packet previously came in
on fxp0 or is now exitting fxp0.
recv fxp0
will match a packet that was received on fxp0
xmit fxp0
will match a packet that is exitting fxp0.
Use recv and xmit, via can be very misleading (imho).
"via fxp0" can also be written "{ recv fxp0 or xmit fxp0 }".
in/out has no relations to "via" as they are independant options.
