@Sebastian-Roth
Dear Sir,
I would like to request you to help me…  I have some doubts…
What exactly is your question?  ->
#This  enp1s0 is for FOG SERVER (Static)
auto enp1s0
iface enp1s0 inet static
address 192.168.147.XXX
netmask 255.255.255.0
network 192.168.147.0
broadcast 192.168.147.255
#This enp3s0 is for Our Organization to access Internet and Local Sharing Extra #Extra… (Static)
auto enp3s0
iface enp3s0 inet static
address 10.12.2.XX
netmask 255.255.254.0
network 10.12.2.0
broadcast 10.12.3.255
gateway 10.12.2.XX
dns-nameservers 10.10.1.XX  8.8.8.8
I configured above IP Addresses statically and
ran the sudo /etc/init.d/networking  restart
OUTPUT :  It gives  OK message …Everthing is running properly and correctly.


Now My Questions Are :
- 
Is it required Router Address for FOG Server While Configuring IP Address For enp1s0? 
- 
FOG asks a Router Address for DHCP Server?[y/N]…  Here I said No Because I have not mentioned Gateway Address in enp1s0…  Is it correct way of
 understanding of myself?
 
- 
FOG asks -> Would you like DHCP to handle DNS? [Y/n]… Here I said Yes
 Again FOG asks -> What DNS address should DHCP allow[10.10.1.2]… Here I Pressed Enter Button…  FOG has taken Default DNS…i.e. 10.10.1.2–>> Is it correct way of understanding of myself?
 
5)My Kind Request is >  What is standard Configuration For FOG Server ?
- One More Request is > What is standard Configurations need to be done For FOG Server… So FOG Server gives BEST Performance?
I would like to request you sir to answer my doubts…
Warm Regards,
