Hm? Seems to me you should have IP forwarding DISabled, and the firewall
should be responsible for forwarding all traffic (Even in a packet
filtering environment). If the kernel can forward packets across
interfaces, you're asking for trouble. (Firewall gets disabled or
otherwise, OS happily forwards ALL packets. Not the situation you want to see)
