# Howto add a IP alias on the "green" interface in IPfire
|
|
|
|
Let's say you have a an internal /24 network and you want to add a secondary (local) IP address (this could be useful in case you remove an old machine from the network and your new firewall is on a different address - but your new firewall should offer on of it's services on the old address).
|
|
|
|
In the ipfire GUI this is not possible. But you can use the file "rc.local" (which is executed while the firewall boots).
|
|
|
|
## 1.) Add the following lines to the file /etc/sysconfig/rc.local:
|
|
|
|
```bash
|
|
ip addr add 192.168.89.1/24 dev green0
|
|
ip addr show green0
|
|
```
|
|
|
|
## 2.) Make it executable:
|
|
|
|
```bash
|
|
chmod 0755 /etc/sysconfig/rc.local
|
|
```
|
|
|
|
## 3.) Reboot your firewall or execute the script manually
|
|
|
|
READY.
|
|
|
|
The new ip address will be automatically configured every time the firewall reboots.
