Re: [Fwd: Re: [LARTC] 2 internal NIC's in the same network]

hi,
I have set arp_filter to 1 at both eth at PC1.
then I ping eth2(10.0.0.2) from pc2 (10.0.0.3)
and both eth1 and eth2 answers to arp request
from pc2.

it seems to be, that arp_filter is not the proper solution for me,
i must apply hidden patch from

 http://www.linux-vs.org/~julian/#hidden

as advice to me martin.a.brown.

bye
