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

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

Restart the newtork service:
# service network restart
Restarting network (via systemctl):                        [  OK  ]

# route -n

Still no changes

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?
