Outgoing shaping (LAN --> WAN) makes sense as your input rate to the router
is at LAN speeds while its output rate is at (relatively low-bandwidth) WAN
speeds. A good set of rules will provide significant performance benefits
for critical apps, while relegating non-critical ones to a "best effort"
basis.
Shaping incoming traffic with queueing technology (WAN --> LAN) does not
make much sense as queues would occur after packets have crossed a
(presumably congested) WAN link, to be forwarded by the routing engine to a
10, 100 or 1,000 Mbps infrastructure. Queues in such a case add unnecessary
latency and provide no real benefit.
