18.5 IP subnets and IP routes
When you have made your network design, where the level 2 is separated and you IP routing is
available you need to care about correct IP addressing, subnets and routes. Altough your internal
AXUM configuration will function without problem. These IP addressing are necessary for:
- Configuration
- NTP time synchronization
- Remote access.
First you have to define a different subnet for each separated ‘level 2’ network. Lets say:
Network
Axum 1
Axum 2
Office
network-address
192.168.1.0/24
192.168.2.0/24
192.168.0.0/24
Where 192.168.1.0/24 also may be written as:
IP Address : 192.168.1.x
Subnetmask : 255.255.255.0
Gateway : 192.168.1.y
DNS : <IP internet DNS Server> or <IP of modem/router>
For your information we have added IP information to practical solution 3:
When you no want to reach AXUM 1 and AXUM 2 from the Example office PC it is required make
static routes. This because:
- all network addresses 192.168.1.0/24 need to be send via 192.168.0.11
- all network addresses 192.168.2.0/24 need to be send via 192.168.0.12
in the windows command line you can add permanent routes:
route -p ADD 192.168.1.0 MASK 255.255.255.0 192.168.0.11
route -p ADD 192.168.2.0 MASK 255.255.255.0 192.168.0.12
The same static routes are required if you want that the modem/router can access those subnets. You
want the modem to access the subnets in case of remote access from internet. See the modem/router
manual how to make static routes.
