Open NAT and two xbox's. Playing Halo 2. Australia, ISP is Internode.
For background, if you don't know what I'm talking about when I refer to open NAT, you may want to refer to the following:
I have an understanding it has to do with UPNP, and perhaps the degree SPI in the NAT implementation.
I Know that port forwarding and putting the client in the DMZ will solve the issue if i only have one xbox....
I have two xbox 360s.
I am using a web excel (no name) AL-2108TC modem/router - supports UPNP, turned on.
Both xbox's report open NAT - when both are connected or each separately.
When only using one xbox we seem to have no worries - what you would expect with Open NAT.
But when we are using both xbox's at the same time we have problems connecting to some users : ( with one of the xbox's - which one can vary. (sometimes cannot hear peoples voice and vis versa in pre game lobby, some people cannot connect to game)
Is there a way around this problem?
Can you change what port the 360 uses for xbox live that i can port forward to two different ports? (due to the nature of p2p gaming - I'm not sure that this would work anyway).
