Hello, assuming I have a friend, Bob. He has two IP addresses and wants to contribute to the tor network. He doesn't want to operate an exit, relay or bridge himself, though. I offer him to operate the bridges on my hardware and he's magically forwarding the required ports from his machines IPs to my machine so I do the relaying part of the bridging game. Bridge users benefit from the additional IP addresses that have to be blacklisted. I'm looking for a way to implement this. I could only think of *) inetd + nc *) dark iptables nat magic *) some sort of ip-over-ip tunnels which would all be kind of hacky, require installation of addition software and would probably have sideeffects on tors bridge stats. Can I announce an address that isn't directly mine? Can I use my address for outbound traffic to the next relay or do I need to use the "bridge address" for that? Is there a flaw in there? Is somebody already doing that? I'm putting this up for discussion. If I can get this working for Bob I could probably get access to some subnets from Charlie and Dave.. Waiting for input. Truly yours, Alice.
