I found the the following sysctl variable But am unsure about what it does. I cannot find any documentation on it. net.link.ether.inet.useloopback It is currently set to 1, so enabled. I had a comment from someone that the kernel uses the loopback interface to Pass packets destined for itself (not nessasarly just the 127.0.0.0/8 network), maybe this will stop the kernel from performing this action and drop it onto the wire the ip address is bound to.
