Sorry I don?t have time to see if this is actually your problem, but I
have the exact set-up using the configure scripts (except for one
thing). The only noticeable difference between what I have and what you
have is that I have an address for eth0 and eth1 in addition to the
aliases I create. Should be simple to try. Set-up eth0 to be
192.168.100.10 and eth1 to be 192.168.8.10 and rerun the config scripts.
