Configuring the routing table
Configuring the routing table
1. Select the NK8237 firewall node.
2. In the Routing tab, click the Add button to add a new route.
3. Configure the following parameters:
- Applying standard IP addressing concepts, enter Destination and Netmask
to describe the destination range on an external subnet.
For example, destination 192.168.2.0 and netmask 255.255.255.0 defines
any address in the range 192.168.2.0 to 254. Instead, destination
192.168.2.10 and netmask 255.255.255.0 defines the single IP address
192.168.2.10.
- Enter the IP address of the Gateway, on the same subnet, which can
provide connectivity for the destination subnets.
- If multiple routes are available for the same destination, use the Metric field
to indicate the cost (e.g. the number of devices along the network path) of
