Accessing Remote Resources across a Virtual Private Network
SonicWALL VPN Clients, which cannot transmit NetBIOS broadcasts, can access resources across a
VPN by locating a remote computer by IP address. For example, if a remote office has a Microsoft
®
SQL server, users at the local office can access the SQL server by using the server private IP
address.
There are several ways to facilitate connecting to a computer across a SonicWALL VPN:
•Use the Find Computer tool
•Create a LMHOSTS file in a local computer registry
•Configure a WINS Server to resolve a name to a remote IP address.
