Run a Service On Another IP

Want to run your service on an IP other than your machine's main NX3 IP? You can do that!

All you need to do is create a dummy interface on your machine by creating 2 files in /etc/systemd/network

First up is the dummy device itself:

/etc/systemd/network/10-dummy0.netdev

[NetDev]
Name=dummy0
Kind=dummy

And then the further configuration information, just make sure to replace the address with your own:

/etc/systemd/network/20-dummy0.network

[Match]
Name=dummy0

[Network]
Address=172.24.1.2

After that, you can reload the systemctl daemon, and the network configuration with the following commands:

sudo systemctl daemon-reload
sudo networkctl reload

Now that you have the network interface created, all you need to do is change the IP address the service listens on!
