Bump. Thanks for keeping this issue in the forefront. Agreed...Serious issue that needs to be addressed, quickly! Appreciate the links for both a workaround and feedback to Activision. I'm in the same boat, want to play using more than one console on the same home LAN, could do so just fine until this local MM "issue" cropped up. Just based on the numbers of people sounding off here in the forums, you'd think we'd have Bungie's attention. Help us out, Bungie! Lots of people here saying they just want to enjoy playing.
