I recently had Fios installed and they provide a router/modem Actiontec M1424. I have it set up so I am still able to get wifi off my airport express since it provides faster wifi speeds. I am having a problem with xbox live. I keep getting NAT moderate instead of open. I opened ports 3074 and 88 in airport utility but no luck. Is it because it is going through two routers? Anyone have a similar setup and have an open nat? The reason I choose not to use the actiontec is because on live the connection is terrible but I have an open nat.
