Dolphin, the GameCube and Wii emulator - Forums

I'm new to Dolphin and I'm using version 4.0-5681. I followed this guide for installation and configuration. I am trying to use netplay, and it works amazingly well when someone else hosts me directly. However when I try to host a netplay session directly people are unable to join. Attempting joining traversal crashes my netplay and my hosting attempts have caused other people's netplay to crash.

I have allowed Dolphin through my computer's firewall and tried opening the relevant ports for my wireless router and I don't know what else to try. Any help would be appreciated.
