XPenology installation not working on my LAN

[Vereato]

Hi there i try to install the DSM on DELL Server  R610  but no success 

 

i follow all the tutorials to setup the grub file  i did all perfect step by step  

 

but when comes to the LAN  detect from Synology Assistent  not working  

 

LAN IP shows on the windows arp -a  the list of the IPs on the LAN Network 

 

is the problem  because i use Synology Router it may cause to  block the Hacking NAS  right 

 

i use Synology  router  it may block the LAN  IP  

 

it shows on the arp -a   windows   the DHCP  network  IPs   but on the router doesn't show  the IP  

 

any help is welcome thanks
