So I may have gotten things sorted out on this. I set up a static IP for the Xbox and used the settings in this link. http://forum.netduma.com/topic/10283-how-to-find-your-best-settings/
The Geo Filter is working GREAT with NHL, with very low pings and connections to only nearby opponents. For FIFA, it's a bit difficult to find a match with someone nearby using the Geo Filter, but that may be due to a very low user base currently. It is only the EA Access trial players that are online ATM. I could see plenty of players over in the UK, however.
I will post a follow up here to let you all know how things are going.
