Connecting 2 pc's to one game

This has probably been answered a million times before but is confusing to a beginner. I have followed the unity documentation's network tutorial and as far as I can tell it does not say how to connect 2 pc's (laptop + desktop) to one server (hosted on desktop.) I am using the basic network manager + hud and have been able to set it up so one instance of the game can connect to another but only on the same pc. Basically, how do I connect one instance of the game on my laptop to the one on my desktop? Help please!

 

Kinda found the answer (i think) by looking in the documentation: http://docs.unity3d.com/Manual/UNetDiscovery.html

However now I have the difficulty of getting this to work which it isn't at the moment.

 

Tried this yet? (First post, see attachment)

 

Fairly sure this is the same one as in the unity manual

 

Okay, so I guess you've read that article then.

All you need is an external IP address from one computer, and the other computer start a LAN Host. When LAN Host is ready, enter the IP address in the textfield where "localhost" is, and press Start LAN Client for the other computer. You should immediately connect.

If not, check your network settings, connections, and other things related.

 

It said in the dev console (on client): 'unet client disconnect error: timed out' ... soooo

 

Are you sure you put in your external IP address (Replacing "localhost" with something like 13.86.15.213)? If yes, then it is your router/modem connection issue, and not Unity's.

 

i googled 'what's my external ip' is that right? Also if it is a router/modem issue how would I go about fixing it?

 

1. Yes. It should show you your external IP address.
2. PortForward.com

 

I know how to port forward but wasn't sure which ports to portforward, so i did both 7777 and 47777 (tcp and udp) but with no success.

 

I think 7777 is already used. May try a different port number.

If that also doesn't work, then I really don't know.

 

Ok, will try that when I get back to my pc, thanks for the help!
