Minecraft wiki entry for Nether_hub, associated text: To start, get the coordinates of all your portals in the nether and write them down. Pick two portals to do first. Start at one of them, and create a two block wide path along either the x (or z, it doesn't really matter) coordinate until you reach the z (or x if you started with z) coordinate of the second portal. Then turn towards that portal and continue until you get there. Note that if the portals are on different y levels, you may have to use stairs to make the path line up with the portal frame. You should now have a path between the portals.
