Private server for friends

How do you make a server for just friends using Hamachi?

Create a network in hamachi, message your friends with the name and password (if there is one) of your newly-created network. Go create a server as you would normally, and be sure you type sv_lan 0 in console, after that, change the map to anything else so the server can restart. Tell your friends to use your hamachi IP ( which is written on the top of it’s window, Example: 5.34.123.44). They can use the console command: connect (IP)

This usually works on normal causes.
