sql-server-2008

I have a SQL Express 2008 R2 server running on a server in an internal lan network. A few databases are used by some third party software to store data. A SQL-Server user is used by this application to connect to the database.

Now I need to access this database using a local installation of the software from an external pc. In this particular case a VPN connection is not the solution I am looking for. I have access to an external linux server, so I tried ssh tunneling from the windows server to the linux server and use the external pc to tunnel it back from the linux server to the client, but this is working very very slow.

What are my other options to allow this external connection in a safe way?
