Open your port and keep the server online 24 hours? Did you even read the topic?
Here's a small summary:
I made a LAN server for me and my classmates. But i can't get the ports open. Robbster said that it wouldn't be possible to open them, since it was at my school.
*End of summary*
Wait... At home, i don't have any more/less access to the internet then i do at school... why can i open ports here, but not at school? (BTW, i haven't been able to open ports at home either yet... (Tried several tutorials.))
Please give me a VERY detailed walkthrough of how i open ports. So that I can try if it REALY doesnt work.
(If i manage to open them here at home, but not at school, i'll finaly give it a rest.)
Whatever
If your classmates are using the same network, you can just open a LAN server without opening ports, I guess. For opening ports I'd need your modem/router brand and model.
