've been trying to play with my friend on PZ for a while now. We followed all the instructions onhttp://www.reddit.com/r/projectzomboid/comments/28xzzz/server_setup_guide_build_271/ , and I have port forwarded using ports 16261 to 16265, and still my friend cannot connect to me. So, my question is, what can I do to play with him? It is NOT on LAN. Please help!
