I'm getting an insufficient MTU rating on my Xbox 360. It needs a minimum of 1364. My Tweak test is saying Max packet recd (MTU) 1470. I'm assuming this is my actual MTU setting. I've got all my ports opened for the xbox 360, and I even have it set on DMZ.
Under observations in the Tweak test it says Upload packet less than MTU, however my Path MTU discovery is ON... So I'm assuming this is why my xbox is giving me this error.. but I don't know how to fix this issue. Under faq it tells me to turn path MTU ON.. but it already is.
Any help appreciated.
