ADDING A GATEWAY ADDRESS

[root@slave network-scripts]# nmcli con show –active
NAME UUID TYPE DEVICE
CocoChopper e8f14903-4b12-44b2-9e15-a9d47c720d14 802-3-ethernet enp0s3
hostonly febb8ba7-a989-40a7-8683-53388f70da39 802-3-ethernet enp0s8
In /etc/sysconfig/network-scripts, there will be a ifcfg-CocoChopper file which will need to be modified.

[root@slave network-scripts]# cat ifcfg-enp04
TYPE=Ethernet
BOOTPROTO=dhcp
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=enp04
UUID=e8f14903-4b12-44b2-9e15-a9d47c720d14
DEVICE=enp0s3
ONBOOT=yes
We can now add the gateway address in the configuration file.

[root@slave network-scripts]# vi ifcfg-enp04
TYPE=Ethernet
GATEWAY=10.0.2.254
BOOTPROTO=dhcp
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=CocoChopper
UUID=e8f14903-4b12-44b2-9e15-a9d47c720d14
DEVICE=enp04
ONBOOT=yes
