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. Henning On Jun 3, 2010, at 3:53 AM, Yoav Nir wrote: > Hi Lars > > Great study.

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. > > -----Original Message----- > From: ietf-bounces@xxxxxxxx [mailto:ietf-bounces@xxxxxxxx] On Behalf Of Lars Eggert > Sent: Wednesday, June 02, 2010 6:37 PM > To: ietf@xxxxxxxx Discussion > Cc: nat-study@xxxxxxxxxxxxx > Subject: Re: wanted: your old NAT home router > > Hi, > > FYI, a first report with test results for 34 devices is available athttp://fit.nokia.com/lars/tmp/2010-hgw-study.pdf.
