This was discussed before, you can check the devl archives.  The
conclusion then seemed to be "it isn't worth the hassle" which I thought
was strange-- the original complaint was by someone (I forget who) whose
external IP changes daily, if not more often.
I tried to point out that it's more hassle for the end user to update his
config every time his IP address changes, especially when he may not even
know precisely when it has changed (other than by noticing that his
freenet traffic has suddenly dropped to zero).
I don't believe any subsequent conclusion was reached.

You're right, the current situation is a bit mad.  I'd like to see replies
from the other nodes saying "here's the data I'm sending you or a
connection response or whatever but hey, this is what your IP address
looks like to me".  Wouldn't that be just super?  It means external IP
address detection would even work when you're behind a NAT (though of
course you'd still need to config your NAT to route the port, but that's a
one-off change, and finding out your external IP address for some brands
of 'plug-and-play' DSL/cable routers is way more difficult than asking
said router to forward a single TCPIP port)

Could we please open this up to discussion again?  Why can't the nodes
reflect the 'observed' return IP address in at least some of their
responses?  (Or, of course, do they already? Or supposed to?)
