I use ETsnitch to view logs, but instead of using the ETconsole.log, try using the games_mp.log instead. I'm using ETsnitch v1.5.0 which I believe is the latest. Give that a shot if you haven't already.
I'd recommend checking out dedicated server hosting first. I've used gameservers.com in the past as both a redirect and a game host.They are decent for the most part but generally overpriced for what you get. I also had a period of time where the server I was on got constantly flooded and crapped out. Its one of the reasons why I switched over to dedicated hosting. They use better hardware and I've had very few issues.
