I just got PM running and connected to the server. On my client, is says 'Xbox Live achievements cannot be earned in this world'. The server is set to survival (and has never been creative). I've got some port forwarding issues and the server reports as 1.0.7 (connecting client is 1.0.8) - so I'm not sure if the 1.0.7 is preventing achievements, but if PM doesn't support them at all then I don't want to bother fixing these issues and I'll just renew my realm. Thanks!!
Cool, thanks for the quick response! I think I'll just go ahead and set it up as a creative mode server for my nieces and nephews to mess around then since I've gotten this far, if I can figure out the port forwarding stuff. I'll open another thread for that.
https://portforward.com should be able to help you with that. They have instructions for almost every router model. EDIT: Sent wrong link by mistake. Fixed it.
It's on a campus network so I don't have access to make any changes to the router and would have to submit a ticket for it so I'm not sure I would be able to find help there or not (but I will check). I asked for an external IP and got one, and I can connect on port 80 (tested with IIS - running on Windows Server 2016), but I don't seem to be able to make a connection to 19132. Not sure if I should try using port 80 instead (with IIS role removed) or if I need to put in another request to have 19132 specifically forwarded.
You'll have to forward port 19132 on both the tcp and udp network protocols (or at least I do anyway) for it to work properly. While you may technically be able to use port 80 for PocketMine, I would highly not recommended doing so, as that is the standard port for a web server, and could cause problems. Especially, if you or someone else is already running a web site on the network.
