I just enabled wake on LAN in windows network driver and now linux works.

Now this dhcp server works fine; and there is no need of any acl rules 
in asa.
Only dhcprelay configuration on interfaces.

I have started secondary dhcp server;
In cisco asa i defined this second dhcp server;

When there is first dhcp server or two dhcp servers runing everything 
works fine;


If there is only secondary dhcp server there is problems geting ip address;
Some times client gets its ip, some times not. Windows and Linux working 
the same way;
Secondary DHCP server sends all packets that is needed for dhcp client. 
And DHCP client not all packets gets from DHCP server;
I't seems, that asa is dropping some packets. Is this a bug? (i'm using 
asa722-22-k8.bin asa software version)
