Configuring Static Networking and IPv6 on CentOS 7 – AKLWEB HOST LLC Support Center https://support.aklwebhost.com Fri, 06 Dec 2019 18:55:07 +0000 en-US hourly 1 https://wordpress.org/?v=6.4.4 Configuring Static Networking and IPv6 on CentOS 7 https://support.aklwebhost.com/knowledgebase/configuring-static-networking-and-ipv6-on-centos-7/ https://support.aklwebhost.com/knowledgebase/configuring-static-networking-and-ipv6-on-centos-7/#respond Fri, 06 Dec 2019 00:46:21 +0000 https://support.aklwebhost.com/?post_type=manual_kb&p=2510 AKLWEB Host has recently made changes on their end, and everything should now work fine ‘out of the box’ with NetworkManager enabled. Should you wish to disable NetworkManager, you can follow these steps.

Pasted below is an example /etc/sysconfig/network-scripts/ifcfg-eth0 file. This template configures IPv4/IPv6 statically. Substitute DNS/HWADDR/IPADDR/GATEWAY/IPV6ADDR from your existing configuration.

DNS1=123.123.123.123
ONBOOT=yes
BOOTPROTO=static
DEVICE=eth0
IPADDR=123.123.123.123
PREFIX=23
GATEWAY=123.123.123.123
DEFROUTE=yes
NM_CONTROLLED=no
IPV6INIT=yes
IPV6ADDR="2001:1234:1234:1234::64/64"
IPV6_AUTOCONF=yes

Then, disable NetworkManager and restart networking:

systemctl stop NetworkManager
systemctl disable NetworkManager
systemctl restart network
