It would be really nice to get one of the consumer PC rags to pick up this
story - an easy-to-interpret compliance label would be even better. If the
consumer rags would refuse to recommend a non-compliant box, maybe vendors have
some incentive to read the RFCs.
I assume IPv6 tests are planned?
This illustrates that the Internet experience will be increasingly driven by
the laziness of equipment vendors, rather than anything the IETF can
standardize. There does not appear to be any functioning feedback loop to
accelerate convergence to reasonable behavior.

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
