To avoid dropping packets by kernel on high load (debug messages like nf_queue: full at 1024 entries, dropping packets(s)) please increase parameter NFQNL_QMAX_DEFAULT from 1024 to 8192!!
This parameter defined in file net/netfilter/nfnetlink_queue_core.c of linux kernel source, that using kerio control.

Nice idea.
The kerio control engine is too sensible to DDOS attacks, it doesn't detect and close correctly the half-open connections in a DDOS attack. It's really easy to make it unresponsive also with a badwidth of 200Mbits only (xeon, 8GB, 6 core).
