Can I use DirectIP behind a NAT, router or firewall?
AOM was engineered to be played over ESO if you are using a NAT, router, or firewall. AOM games played over DirectIP (non ESO) require a direct internet connection and do not officially support these network devices. If you are trying to set up a DirectIP game behind a NAT, firewall or router, and your machine has a “fake” IP address (such as 198.something or 10.10.something) you will need to plug your machine directly into the internet so that you have a “real” external IP address before attempting the DirectIP game.
