NetBIOS Relay Application

The UDP relay function in the switch extends b-node functionality across the internet. An
example application is shown here.
NetBIOS Relay Application
In this example, NBNS and NBDD relays should be configured to forward to VLAN 10 and
VLAN 20. The VLANs must be selected for forwarding, or you can configure the subnet address
of the VLANs as next-hop addresses. The server addresses could be configured as next-hop
addresses, but since the assignment of the NBNS and NBDD servers are by definition dynamic,
configuring the VLAN number or the IP address of the VLAN ensures that the relay will func-
tion even if a server address changes.
