We cannot therefore increase the delay over that amount. That is the unfortunate reality; everyone is NATted, and it's a PITA, but that's life. > > As I understand the current system, it's a formula based on the age > of the build, the time we've seen it most recently, how often it's > connected, and other factors. > > I think it might make sense to make this value increase > exponentially, until it hits a max value, set in freenet.ini > Ie, Start at 10 seconds, go to 1 minute, then 1 hour, then every 10 > hours.

We did this in 0.5. We can't do it any more because of short tunnel timeouts on NATs. > > Transient nodes aren't hurt, since if the node RECEIVES a packet from > the Just-started transient node, it will immediately consider that > node current.

We can do things like this if we are SURE that the port is forwarded, but even UP&P isn't reliable from what I have heard. So we have to assume that most connections will need UDP hole punching. > > I'm thinking about implementing an exponential scale in my build, but > I think it makes sense to have it generically. -- Matthew J Toseland - toad at amphibian.dyndns.org Freenet Project Official Codemonkey - http://freenetproject.org/ ICTHUS - Nothing is impossible.
