IP Office Integral Layer 3 Switch
Layer 3 switching is particularly useful in situations where it is desirable to have a trusted and unsecured network, where the unsecured network is uncontrolled and carries public traffic on it. It is possible to set up a firewall between two LAN segments using the IP Office layer 3 switch. IP500 V2 supports a two-port Layer 3 Ethernet switch with the firewall between them. Both of these switched ports have their own IP addresses (LAN1 and LAN2) and in order for traffic to pass from one port to the other, a route is configured in the systems routing tables.
