I had 2 issues that were fixed in the 3.12NA firmware, but now with 3.12NA I have a few issues I'd like to report.
I have 3 Xbox 360's connected to the router, mine is directly connected to the router, while my brothers and his fiance are connected to it via a Netgear switch.
the first one to turn on their Xbox 360 gets an OPEN NAT type to Xbox Live, while the other 2 get a MODERATE NAT type.
I've reserved an IP for each console, and port forwarded the ports listed on Xbox.com to each console, but it only works for 1 machine.
as for the other issues I'd like to report are.. it now displays that a devices IP address will "Nerver" expire, I imagine this means "Never"
issue 3 which was discovered sometime in May or June is that UPnP no longer works correctly or at all.
