note that net mask?    the loopback interface is the entire 127.0.0.0/8
network    you can't put a host at 127.0.1.x and expect it to work right.

you should instead use one of the RFC1918 reserved subnets for a private
network, within 10.0.0.0/8 or 172.16.0.0/12, or 192.168.0.0/16  (you can
use these with any mask size you want, for instance, /24 is usually used
with 192.168.x.y)
