I tried 11.0-CURRENT r274549 with and without patches. Without patches all works as expected. System encrypts and forwards traffic with and without aesni module. With patches software rijndaelEncrypt also works. But when I load aesni.ko and restart setkey -f /etc/ipsec.conf forwarding stops, errors counter starts grow. And I see messages about wrong source route attempts from random addresses. --=20 WBR, Andrey V.
