I remember this. It seemed to me like you originally said that you had
more than 256 ip addresses. Maybe 512?? which is a /23 network ?
And I said to use a mask to fit your /23
But 255.255.255.0 is a mask for a /24 network (256 ip addresses)
So if your address range is 1.2.0.0 to 1.2.1.255, I think the mask would be
255.255.254.0
OUTERNET=$OUTERIP/255.255.254.0
What does ifconfig eth0 say your mask is?
