If I have one proxy server with a static public IPv4 198.51.100.138 which can access interent.
How many client PCs in a local network can access Internet via the proxy server ?
I use MS SQL 2017 Express Database server in my Windows 2016 server.
I hope to expose MS SQL 2017 Express Database server to the internet, so I need open 1433 port in firewall.
But I find there are two options, local port and remote port, you can see Iamge 1, what are different?
What option should I set to open 1433 port for public internet?

I use MS SQL Server 2017 Express Database in windows 2016 server, I am seeing that the ERRORLOG file of MS SQL Server is increasing 600MB per day.
The below is from the ERRORLOG file.
Does this mean that my MS SQL Server 2017 Express Database is being attacked?
How can I fix this problem?

I order VPS hosting with Windows 2008 server and a dedicated IP Address , and install IIS 7.5 and DNS services on the server,I hosted 3 websites on the server, it works well, and I can use my domain to access my website, now I hope to use IP address to access my website, how can I configure IIS? Thanks!
