Port open on Windows Firewall after installing SQLServer2008

1. Open the Protocol for SQL Server Configuration Manager-->sql Server network configuration-->xxx, enabling the TCP/IP protocol
2. Open the properties of the TCP/IP protocol, cut to the "IP Address" tab, pull to the bottom ipall, empty "tcp dynamic port", and fill in the desired port number in "TCP Port".
3. Open the Advanced settings for Windows Firewall, create a new rule in the inbound rule, and open the required port number.
PS: If you need to open a different port number for each IP on the server, and change "all listening" in the "Protocol" in "TCP/IP Properties" to "no", the Ipall will fail.
