I'm having some issues with Internet access from CentOS7 server which is installed in Vmware Workstation 10.0.3 build-1895310 in Windows 7 x64. At this point I can't get if the error is on CentOS configuration or it's another problem so I leave here what I did in order to get Internet working on that VM.

Ok, since my default route is bad,
# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 192.168.3.1 0.0.0.0 UG 1024 0 0 eno33555200 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eno16780032 192.168.3.0 0.0.0.0 255.255.255.0 U 0 0 0 eno33555200
I tried this two ways:
1) */etc/sysconfig/network* Add line GATEWAY=192.168.1.1
Restart the newtork service: # service network restart Restarting network (via systemctl): [ OK ]
# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 192.168.3.1 0.0.0.0 UG 1024 0 0 eno33555200 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eno16780032 192.168.3.0 0.0.0.0 255.255.255.0 U 0 0 0 eno33555200
Still no changes
2) */etc/sysconfig/network-scripts/ifcfg-eno16777728* Add line GATEWAY=192.168.1.1

What I'm doing wrong? Every time I do a network change/configuration I need to restart the complete OS in order changes to take effect, why?
