Hi,
I have a firewall box running 2.2.7 and ipfilter. On one ethernet
interface I have real addresses and on the other I use 192.168.0.x.
Everything was going great until yesterday. Someone plugged a machine
into the dirty side of the network with the same 192.168.0 network address
that my machine on the clean side of the firewall uses. For some reason
the "intruder" box kept being recognized as "the" 192.168.0.2.
Why is that? I would think that if you have two machines claiming the
same address the one that is attached to the right network would win. Is
there any way to lock this down? 'arp -s' doesn't seem to make it
stick...
Thanks,
Charles
