I read this a few times and still didnt get it:
Why is it that people using 1918 addresses are affecting you?
Does using 127.x help you because you assume _nobody_ else would be using
127.x addresses?
I am assuming you want this address for some internal network whereas the
external contains some routable addresses?

Seems you did too much. Look at the 2 liner patch posted by Eran Mann
(which should work on 2.4 and 2.6 as well).
