SQL Remote Connection Error 26 with pictures

Question

Hi.
I am trying to connect SQL Server 2012 via internet, but I cannot. I do the following steps:
1- I tuned up my modem settings for port forwarding to my computer: (TCP: 1433, UDP: 1434, Computer Name: TURAN, LAN IP: 192.168.1.27)

Hi alazarbaharu,
Agree with Kiran. And  also put sqlbrowser.exe into Windows Firewall exception.
According to your number 7 link, I got that you encountered a failure when using sa account to login in SQL Server. To troubleshoot this issue, please follow the steps below.
1. Make sure that SQL server is in mix authentication mode. In SQL Server Management Studio Object Explorer, right-click the server, and then click Properties, on the Security page, check Server authentication. After changing the authentication mode, we
need to restart SQL Server.
2. Make sure the sa login is enabled in SQL Server. In Object Explorer, expand Security, expand Logins, right-click sa, and then click Properties. On the Status page, check if the sa login is enabled, and on the General page, confirm the password.
Thanks,
Lydia Zhang
