Please reduce your BandwidthRate until your relay load is what you want it to be, or wait until the bandwidth authorities notice your relay is overloaded and reduce its consensus weight.

Dropping packets using IPTABLES will actually increase your relay’s load due to retransmits, and degrade the performance of clients which use your relay. An IPTABLES rule would also degrade the performance of the overall Tor network due to these same retransmits.
