Changing Network Interface on Centos

Now I’ve got wired connectivity into the basement, I dont need to have the uplink between the comms pc and the router on Wifi. The interface shown here as wlp3s0 will now be called eth1


This article basically describes the process


However, I’ll also need to change theĀ /etc/sysconfig/network-scripts/ifcfg-eth1 file to contain the IP address previously assigned to wlp3s0, and run

ip link set dev wlp3s0 down
service network restart

This is to ensure that incoming requests from the internet hit the new adapter, not the old one, which may be reassigned to something else later on.

Next, I’ll need to check firewalld has kept up with the changes

firewall-cmd --get-active-zones

and check eth1 is in the external zone
