Port forward help? (AmIdoingitrite?)

Am I forwarding the correct ports in the right slots?

Yes you really only need port 27015, I believe. Also there is no need to hide your Ip addresses as it’s internal.

you only need 27000 to 27020

Does it need to be “both” or TCP or UDP and which port-number goes where? and one more question. How do I join my own server?
