Connecto to remote SQL Server

Hi, community

I want to connect a program (like query analyzer) in home, to the sql server in office via internet, but i can't log in to the remote server. Someone know how to establish the connection?

Thanks to all of you!!!You will need to get permission from you network group to VPN into the network.|||thank you, but can you be a little more detailed?|||You need to talk to your network group and have them give you VPN access and tell you how to use it.|||I've tryed lot of things but cant connect!!!!, i try to establish a VPN in win 2k3 server as Server and winXP Prof as client, but it is impossible to get connected!!!

I finally get the VPN connection, i've missing directives, but now i cant connect to SQL Server!
