16.4 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
Oxygen 5 Digital 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
Oxygen 5 Digital 1 Oxygen 5 Digital 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 Oxygen 5 Digital 1 and Oxygen 5 Digital 2 from the Example office PC it is
required make static routes. This because:
-
all network addresse s 192.168.1.0/24 need to be send via 192.168.0.11
-
all network addresse s 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.
