NETMASK = 255.255.255.0 # Set the subnet mask
GATEWAY = 192.168.204.2 # Set Gateway (Gateway review steps, vmware workstation == "edit == "virtual network editor ==" point VMnet8 mode == "the NAT setting ==" gateway the IP)
the DNS1 = 119.29.29.29 # set the primary DNS
DNS2 = 210.2.4.8 secondary DNS setting #
