Problem connecting to MSSQL via remote connection

I have a problem connecting to MSSQL from my program (Win App).

It worked few week ago, but now just says Sql server doesn’t exist.

I don’t know what’s wrong.
I have a ADSL connection, maybe this is a problem (before, I had a dialup and worked ok) because I might have a private IP.

Can you tell me what is going on?
Connection strings are ok.

Is it ADSL (private IP) issue or something else?

Thanks.

I’ve connected via dial up, and now it works, so it’s ADSL issue.

It is likely that they have blocked the ports on your ISP :frowning:

Unfortunately, I think so too.

Can port redirection solve the problem?
It seems that I have to remake this app as web app.
