No Traversal drop down option

[youngtech]

my friend and i are trying to play netplay on SSB melee and this is our first time using the emulator and it seems like i have the option to use traversal like in the drop down menu on the top left and my friend doesn't.... his just seems like its already on direct and there is no traversal.... so he can't put a host ID in, its just the IP address he can put in. can someone help??
