If you are only using .NET clients then WCF should work. Webservices would also do the job.

>Using IP connection string or something else which is simple ?

For you would need to open your SQL Server onto internet which is not desired and most firewalls would block the connection anyway.

What I mean simple is we don't have to change the way we fetch data from LAN SQL server, but just change the connection.

Thank you.

Is this server on LAN or WAN? If WAN then it wont be very simple. As I said, you would be exposing your database server on the internet and your hosting company would probably block the port anyway.

It is a web server.
Let's say the company allow us to do it, since it is dedicated web server.

Or let's say it just a company server reside at the company and connected through internet.
The user could use application which reside at client computer from the branch or warehouse somewhere else.

Thank you.

There are usually two options

1) Use tunneling and then the server will be same as if it was on LAN

2) Use one of the options I have previously mentioned.

-1) You can expose the SQL server on web and use it that way but that's not recommended.

Great.

How could I do it using option 1 ?

-1) You can expose the SQL server on web and use it that way but that's not recommended.
We could set the windows server security to accept incoming user  and Ip address. Could we ?

Thank you.

For -1, I do not know the exact details of how to achieve it but I think it will be troublesome

For 1, use VPN. Ask your network administrator.

We don't use VPN just have public/static IP.
