Hi Lars
Great study. Looking forward to seeing more devices there.
Two tests I would add to this:
1. TCP segment size negotiation - have a low-MTU link somewhere between the NAT
box and the server, and see if the MSS gets adjusted like it should.
2. IKE/IPsec - IKE was supposed to go from port 500 to port 500. Some older
routers made heroic efforts to translate the traffic so that the source port
remains 500, which may have killed more sessions than it saved. These days, NAT
Traversal makes this easier. I suggest connecting some IKE/IPsec client (like
the Microsoft or Mac OS L2TP client) to some server through the NAT.

Hi,
FYI, a first report with test results for 34 devices is available
athttp://fit.nokia.com/lars/tmp/2010-hgw-study.pdf. Slides that summarize the
results are at http://fit.nokia.com/lars/tmp/2010-hgw-study-slides.pdf.
We have received another 30-odd devices as donations, which we'll add to the
testbed and include in a follow-up study.
If you have an unused, spare home gateway to donate to this effort, please
contact us at nat-study(_at_)fit(_dot_)nokia(_dot_)com(_dot_) We're also
interested in obtaining a DSLAM and a CMTS.
Thanks,
Lars
