I would use pfctl(8) -F on pf(4) to flush a specific state from the
table.  That will cause the forwarding device / upstream router (or
localhost if you have it enabled).

Either that, or insert a temporary rule that does "block
return-rst" (Which will force the client to reset the kernel socket
structure) for the specific source/destination address.

Most PF users have a pf(4) table (<wankers>) and a referenced standby
rule for use in DDoS situations.
