IP routing
The Connect IT 4device uses IP routes to decide where to send a packet it receives for a remote
network. The process for deciding on a route to send the packet is as follows:
1. The device examines the destination IP address in the IP packet, and looks through the IP
routing table to find a match for it.
2. If it finds a route for the destination, it forwards the IP packet to the configured IP gateway or
interface.
3. If it cannot find a route for the destination, it uses a default route.
4. If there are two or more routes to a destination, the device uses the route with the longest
mask.
5. If there are two or more routes to a destination with the same mask, the device uses the route
with the lowest metric.
