N-TRON 702-W examines the destination IP address of each data packet traveling through the
system and chooses the appropriate interface for packet forwarding. The system choice depends on
static routing rules – entries, which are registered in the system routing table. Static routes to specific
hosts, networks or default gateway are set up automatically according to the IP configuration of all
the N-TRON 702-W interfaces.
