192.168.80.1 is FreeBSD le1 NIC.
As you can see, there are 7 dif. MAC addresses:

1 MAC - 00:d0:89:02:63:78
2 MAC - 00:d0:89:03:b0:80
3 MAC - 00:d0:89:03:b0:08
4 MAC - 00:d0:89:03:93:bc
5 MAC - 00:d0:89:02:63:48
6 MAC - 00:d0:89:02:63:7c
7 MAC - 00:d0:89:02:62:aa

and

8 MAC - 00:50:56:9a:75:9f is my FreeBSD le1 MAC.
When I stop arp on le1:

ifconfig le1 -arp

All PC's with Windows 7 and Windows 2008 do not have internet access.
Also I try to put router:

DVR1 DVR2 DVR3 DVR4 DVR5 DVR6 DVR7
------------------------------------

switch - router - switch - GW

But ARP packets still f*cked up my GW, and Windows 7 drop internet connections.
Why DVR's wana use 192.168.80.1 ?How I can block this packets?
Thanks

 

I dont thing so.
In DVR network setting have only "Network options" from where you can set static IP address ( at the moment they use static IP addresses - 192.168.80.130-137 ) and "DHCP use"
When I put IP from another network - 192.168.90.131 , FreeBSD le1 continue to recеiving ARP packets from this DVR ( 90.131 ).
Only when I power off it, packets stop ( or disconnect ).

P.S. I'm not 100% sure , but I thing DVR's was Dynacolor DG216

 

Thanks, tonight will try to find it.I suppose this options must be somewhere in DVR network config?
