Windows Networking Broadcasts

Netopia firmware provides the ability to forward Windows Networking NetBIOS broadcasts. This is useful for, for
example, a Virtual Private Network, in which you want to be able to browse the remote network to which you are
tunnelling, as part of your Windows Network Neighborhood.
Routed connections, such as VPNs, can not use NetBEUI to carry the Network Neighborhood information. They
need to use NetBIOS, because NetBEUI cannot be routed. This feature will allow browsing the Network
Neighborhood without any additional workstation configuration.
You enable this feature in the IP Profile Parameters screen of your Connection Profile. The IP Profile Parameters
screen varies slightly, depending on whether your model router connects directly to the Internet, or if it connects
via an Ethernet connection through a cable or DSL modem. The enabling feature is the same for both:
Using the Tab key, toggle NetBIOS Proxy Enabled from the default No to Yes, and press Return. Your remote
Network Neighborhood becomes accessible from your Windows desktop.
Note:
The remote IP address and subnet mask should strictly match the IP address and subnet mask
configured on the LAN interface of the remote router. See the following example.
Example:
LAN IP 192.168.1.0/24
PC # A --------- Router A
.100
When PC #A sends a Windows networking broadcast it sends it with a destination IP 192.168.1.255.
When Router A receives this broadcast it translates the destination of this broadcast to match the remote IP of
the NetBIOS Proxy-enabled VPN profiles and it forwards the broadcast through the VPN tunnel.
When Router B receives this broadcast, it sends it on its LAN.
