Is there another way to open this port so I don't get disconnected while I try to play multiplayer games? It's extremely frustrating! Any work-arounds or tips would be great, I can't find anything online in google, youtube, tech support for isp / router, nothing.
Useful information you may need to help:
Motorola NVG510 modem / router
ISP is AT&T U-Verse 18mbps (unfortunately)
