What is the .....

What is the difference between a LAN server and a dedicated server

Hey can you please not cliffhanger titles

LAN = Local Area Network (people playing at your house self-hosted)
Dedicated = Global (seen by everyone near or not near you, can be bought or self-hosted)

But if i start up a dedicated server with gmod/tf2 its only lan what am i doing wrong

Cause you haven’t forwarded your ports or your using the Source Dedicated Server thing.

Ohhhhhhhh but what can i use more than the Source Dedicated stuff
