The problem is that the SIOCSARP ioctl ATM enabled proxy_arp automatically
when you specify a pub entry. So you have to turn it off explicitely after
the ARP setting. The automagic proxy_arp setting is unfortunate IMHO,
because it is really not needed for explicit pneigh entries to work.
It also does not help for those wanting to make subnet proxy arp work
(and use a newer arp utility that sets the mask), because for them
it'll error out with EINVAL.
Alexey, could you explain why you did this ?
