I don't quite follow how you propose to do that with a packet filter?
At least I'm not aware of any packet filter that makes trust decisions
that are not binary.

Provided you somehow route the packets from different networks to
different (virtual) interfaces, you could measure and eventually
compensate the asymmetry associated with that particular network
provided you have some trusted time server on each side of the
