How do I host a server?

[gvazdas]

Hello, I would really like to host a Garry's Mod server.
Problem is - I don't know.
When I host in-game Garry's Mod, people can't connect.
I heard you can connect in Source Dedicated Server, but i can't find it in tools.
Can anyone help?

The reason they can't connect is because you need to forward your ports if you're behind a router.
