I don't _think_ they apply to aliased interfaces other than the fact that the IP(s) will be different. VLANs will need their own rules though as they are a pseudo physical interface. > because in my actual case I would be having 127.x.x.x ips on my > physical interfaces and actual ips on logical interfaces. for > example: > > eth0 - 127.2.3.4 > eth0:0 - 10.19.0.102 Um, be careful using 127.x.y.z/8 on any thing other than the loop back as I think there are hard coded filters in the kernel to protect the loop back. I don't know if it is to protect the IP range or the subnet that is assigned to the loop back interface.

Um, there are some config files on some distros that have this option per say. Rather that is to say that they read the file and set the parameters on boot on your behalf. As far as how to set them and not have them be set on boot, I'm sure you could modify the kernel source. Grant. . . .
