Alright, the problem is this.
I've made a simple, dedicated 1.3 server.
Im quite sure my settings are correct (mtaserver + local). However, my pal IS NOT ABLE to see the server either on internet, or local area network WHEN WE ARE CONNECTED by a normal ADSL (RJ45) cable. We've also tried Hamachi, with and without cable, but still no success.
Also, I opened up all the ports in my firewall MTA is using. Still, no success.
Annnd if it helps, Im running the server on my laptop.
Any ideas?
