## network configuration
The example above fits the most cases. Here a detailed description of possible settings:
### fixed IP
```
enp2s0=192.168.3.5
```
Configure the IP address of the connected device to get the specified IP via DHCP or
configure the device to with this static IP. The last number must be within 1..254,
the APU port itself will get 1 (or 2, if the specified IP is 1).
### custom network
```
enp3s0=192.168.3.1/24 # our ip address, the static address of the connected device must
# be within 1-254 and not match our own
```
24 means 24 bit = 3 bytes network address.
A local network with static addresses. This way, the APU can get an other address than
192.168.x.1 or 192.168.x.2 or the network address size might be defined other than 24.
Probably needed rarely.
### uplink via DHCP
```
enp4s0=wan # or enp4s0=dhcp
```
Uplink configured for DHCP in any network n.x.y.z with n < 192
### customized uplink
```
enp1s0=wan,192.168.1.0/24
```
Add more networks to the allowed uplink range. More than one range is allowed, comma separated.
Must not overlap networks specified for other ports!
### disabled port
```
enp3s0=off # disabled
```
