Using blocking mode on interface p2p with ignore fluid seems to respect the ignore fluid but only for machines directly touching the interface, machines connected only by interface p2p do not respect the ignore fluid and do not have items put inside them.

If this is a cross-mod issue that you either do not wish to fix or cannot fix please ignore and mark as closed.

Unfortunately this issue is equally on both NAE2 and AE2FCR, but since tunnels are on my side, I might look into improving the compatibility.
