Subjectarp: SIOCSARP: No such device

Kernel: 2.0 , Nettools: 1.3.6-BETA5

This is output of my job:

Ondraszek-gw is my router, i am on subnet 3 ( netmask ),
m,y gateway is
The question is why arp does not work. It isnt just add entry: every
attempt to write to arp cache ends with this message.
I dont need this on my computer, but on router it is pretty good thing: I
can make users not to change theirs IP numbers in subnet.
