NAT Settings for Xbox360?

We used to live in London on an 8M broadband line, and used our Xbox 360
easily on the home LAN, via HomePlug 200AV appliances.  I hard-code our IP
addresses, and do not use DHCP.  We have recently moved to Devon, into a
farmhouse sitting on the very border of the exchange's coverage zone, and
BT's techs could only promise as high as [wheeze] 1.5M tops.  So we worked
with our ISP - not BT - to do Bonded Broadband/Tunnelling, whereby we have
hardware at their data centre, two broadband lines at the house here hooked
up to a router each, and a FireBrick modified specifically for this use into
which the routers go; and the FireBrick is hooked up to a router.  The FB is
the only box with a firewall active, and we had to add port 3074 for the
Xbox 360 to access the internet at all.  Xbox Network Diagnostics blame the
NAT we are using, and recommend turning uPnP on at the router, which to it is
actually the FireBrick.  For obvious security reasons we will not turn on uPnP
on the FireBrick. This no doubt complicates the situation as far as the Xbox
360 is concerned.  And, in the meantime, the Xbox 360 is "disconnected from
Xbox Live" after exactly three minutes of access.  This does not make for a
great online gaming experience, or downloading for that matter.

There is actually no problem on the LAN itself, as it exists inside the
FireBrick's coverage.  And, no, it is not possible to hook the Xbox 360
connection up to one of the two routers, as they need to be dedicated
throughputs for the FireBrick.

My question is, what particular settings does one want to use, in place of
uPnP not being enabled?  it is not like uPnP performs some dark magic on the
connection to communicate with the devices that try to contact it.  Thanks
in advance.

It turns out that the FireBrick does NOT have uPnP as an option in any way
shape or form.  I am convinced at this point that uPnP is harmless and only
considered a 'security threat' by Linux, Sun or Apple users or pundits
getting paid to write shock-horror stories.

So what is it that XboxLive wants via uPnP besides ports?  Something's not
meeting its satisfaction, and I am still being disconnected after 2.5
minutes.  You can guess how much fun it is not, especially if buying
something (not enough time to type in a credit card) or wanting to play a
multiplayer game online.

Anyone?
