NETBIOS over VPN at FGT60E router

[krz]

Hello, I have an L2TP VPN access set to a local network and everything works apart from the software that relies on NETBIOS names. Unfortunately there's no way around it - so can anyone give me a tip on how to allow NETBIOS over VPN? So it will act like a full-on local network

NETBIOS is not routable and can't broadcast across segments.  You would need to have a WINS server running with the name and IP of you Application Server in it.  WINS Server is a role you can enable on Windows Server.   Once that is setup, on the application server and remote client, open Properties for your network adapter.  Choose Internet Protocol Version 4 Properties\Advanced TCP/IP Settings\WINS.  Ensure that the IP address of the WINS server is entered and "Enable NetBIOS over TCP/IP" is enabled.

You should also ensure you have DNS and Layer 3 setup correctly.  You should be able to ping the server by name from the client.

That should allow the application server to register its name and IP address and the remote client to query the NETBIOS name and obtain the IP when connecting remotely.

If this doesn't work, then there is some name resolution issue in your application and it won't work most likely.
