NetBIOS rebroadcast
Network Basic Input Output System (NetBIOS) is a protocol for sharing resources among
desktop computers on a LAN. You can configure the Branch Gateway to relay NetBIOS UDP
broadcast packets. This feature is used for applications such as WINS that use broadcast but
might need to communicate with stations on other subnetworks or VLANs.
Configuration is performed on a per-interface basis. A NetBIOS broadcast packet arrives from
an interface on which NetBIOS rebroadcast is enabled. The packet is distributed to all other
interfaces configured to rebroadcast NetBIOS.
• If the NetBIOS packet is a net-directed broadcast, for example, 149.49.255.255, the
packet is relayed to all other interfaces on the list, and the IP destination of the packet is
replaced by the appropriate interface broadcast address.
• If the NetBIOS broadcast packet is a limited broadcast, for example, 255.255.255.255, it
is relayed to all VLANs on which there are NetBIOS-enabled interfaces. In that case, the
destination IP address remains the limited broadcast address.
