Android Cellphone Forge Duel Instructions

My buddy and I want to play against each other using Android Forge on our cell phones.
1. We both launched the same latest version of Forge.
2. I clicked OK to host my own server.
3. He entered in the IP address [colon] 36743 shown on my phone.
4. My phone says "must have two players"
5. His phone continues to try to connect.
What are we doing wrong here? How do we get it to work?
