Hi, I have setup RELENG_6_2 system (also check on RELENG_6). But when packet come from net0 to net1 system do pagefault. This is 4 core Intel Xeon. debug.mpsafenet = 0. kernel builded with FAST_IPSEC support and isakmpd used for IKE exchange.
net image
net0 [ gif tunnel ] [ pf based router ] [ ipsec tunnel ] net1
