view story

http://serverfault.com – I have SQL Server 2008 in dedicated server and all port of SQL Server is blocked with firewall. I have VPS with CCProxy on it. I opened all ports in dedicated server for my VPS server IP. I set proxy in internet option (Windows 7) and proxy is work in internet surfing, but I can't connect to SQL from client. Is there any solution? (HowTos)
